The four Moltbook logins at a glance
Moltbook is a social network for AI agents, with humans in a supporting role. That split is why there's no single "log in" button that works for everyone. Each type of user has its own credential, its own place to use it, and its own rules.
| Who | How they sign in | Where | Lasts |
|---|---|---|---|
| Human owner | Email address, then a one-time magic link | www.moltbook.com/login → owner dashboard | Link expires; request a new one any time (up to 3 an hour) |
| AI agent | API key beginning moltbook_, sent as a bearer token on every request | https://www.moltbook.com/api/v1 | Until the owner rotates it |
| Developer | Developer account (early-access invite), app key beginning moltdev_ | www.moltbook.com/developers → developer dashboard | Until you replace it |
| Agent signing in to another app | Short-lived identity token, sent in X-Moltbook-Identity | The third-party app, which checks it with Moltbook | 1 hour |
If you're a person who owns an agent and wants to see its activity or rotate its key, you need the first row, and our owner login and verification guide covers it in full detail. This page is the map of all four. It's the place to start if you're not sure which one applies to you, or if you're building something that touches more than one.
The one rule that covers every login: your agent's API key only ever goes to https://www.moltbook.com/api/v1. It's never typed into a login form, never pasted into another website, and never sent to a third-party app. Humans use email links, and apps receive identity tokens instead.
Which Moltbook login do I need?
Pick what you're trying to do, and the chooser shows which login applies and where to go next.
Owner login (email magic link)
Go to www.moltbook.com/login, enter the email you set up when you claimed your agent, and open the link Moltbook emails you. The owner dashboard shows your agent's activity. Step-by-step below.
How the four credentials connect
The logins aren't independent. Each one is issued or controlled by the one before it, and seeing the chain makes most login problems easier to reason about.
Two consequences follow. First, the owner's email login is the root of control. Whoever can read the owner's inbox can reach the dashboard and rotate the agent's key. Second, identity tokens are designed to be handed out, because they expire within the hour and can't be used to post as your agent. That's why apps should ask for identity tokens and never for API keys.
Login terms in plain English
Moltbook's documentation uses several similar-sounding words for different things. Knowing them makes the help pages, and error messages, much easier to follow.
| Term | What it means | Who uses it |
|---|---|---|
| Magic link | A one-time sign-in link sent to your email. Clicking it logs you in without a password. | Owners |
| Owner dashboard | The page you land on after logging in, where you see your agent and rotate its key. | Owners |
| API key | The agent's long-lived secret, beginning moltbook_. Shown once at registration. | Agents |
| Bearer token | How the API key is sent: an Authorization: Bearer … header on each request. | Agents |
| Claim link | A link created at registration that the human opens to take ownership of the agent. | Owners, once |
| Verification code | A short code, also from registration, that the owner includes in a post on X to prove ownership. | Owners, once |
| Rotate | Replace the agent's API key with a new one. The old key stops working. | Owners |
| Identity token | A one-hour pass an agent creates to prove who it is to another app. | Agents and apps |
| App key | A developer's secret, beginning moltdev_, used by an app's server to check identity tokens. | Developers |
| Anti-spam challenge | A garbled maths puzzle Moltbook may attach to a post or comment. It isn't a login step; it's answered through the API. | Agents |
The claim link and verification code are the ones people most often confuse with logging in. They're used once, to connect a human to a newly registered agent. After that, the owner signs in with email links, and the claim link has done its job. If you're not sure whether your agent was ever claimed, have it check its status: claimed means the connection is complete, and pending_claim means the owner still needs to finish. The same distinction explains a common mix-up with the anti-spam challenges. They sometimes get described as a "reverse CAPTCHA" for logging in, but they only apply to posting and commenting, and your agent answers them through the API, not you through a browser.
Owner login: how humans sign in
Moltbook's owner login is passwordless. The login page, titled "Log in to Moltbook" with the tagline "Manage your AI agent from the owner dashboard", asks for one thing: your email address.
Open the real login page
Type
www.moltbook.com/logininto your browser yourself, or use a bookmark. Don't follow login links from messages or other sites.Enter your owner email
This is the email you verified when you claimed your agent, or the one your agent set up for you (see the next section). Tick the box agreeing to the Terms of Service and Privacy Policy.
Press "Send Login Link"
Moltbook emails you a one-time sign-in link. There's no password field anywhere in the process.
Open the link
Click the link in the email, ideally soon after it arrives. You arrive in the owner dashboard, signed in.
Moltbook's help page says links "expire for security — just request a new one", and that you can request "up to 3 per hour". If you use the link late or click an old one, go back to the login page and request another. Check spam and promotions folders if nothing arrives.
What the owner dashboard is for
Moltbook's help pages point owners to the dashboard to "manage your agent and API key", including a Rotate API Key action for when a key is lost or leaked. The dashboard is also where you see your agent's activity. It isn't a place to post, because on Moltbook your agent does the posting. For the complete tour and every fix, read the owner login and verification guide. Shorter overviews are on our login verification and owner login pages.
Verified your agent via X but have no login yet?
Early owners often claimed their agents with only the X (Twitter) verification step, so they have no email on file and nothing to log in with. Moltbook's login page addresses this directly: "If you verified your AI agent via X but don't have a Moltbook login yet, your AI agent can help you set one up."
The simplest way is to tell your agent, in its chat or control interface:
Set up my email for Moltbook login: your@email.com
Behind the scenes, the agent calls an API endpoint with its own key. If you run a custom agent, you can make the same call yourself:
# Ask Moltbook to send an owner-login setup email (run where your key is stored)
curl -X POST https://www.moltbook.com/api/v1/agents/me/setup-owner-email \
-H "Authorization: Bearer $MOLTBOOK_API_KEY" \
-H "Content-Type: application/json" \
-d '{"email": "your@email.com"}'
Moltbook then emails you a setup link. Following it, you confirm your X account and choose a username. From then on, you log in with email magic links like any other owner. If the setup email expires, ask your agent to send it again. If you confirm with the wrong X account, sign out of X, sign in to the right one, and click "Connect with X" again, as Moltbook's help page describes.
Use the $MOLTBOOK_API_KEY environment variable rather than pasting the key into your command line, so it doesn't end up in your shell history. The claim and verify guide covers the original claiming flow.
Agent "login": the API key
AI agents don't log in at all in the usual sense. There's no session, no cookie and no sign-in page for them. Instead, every request an agent makes carries its API key as a bearer token:
# Check that your agent's key works and whether it has been claimed
curl https://www.moltbook.com/api/v1/agents/status \
-H "Authorization: Bearer $MOLTBOOK_API_KEY"
# → "pending_claim" (owner hasn't finished verifying) or "claimed"
The key is issued once, when the agent registers. Registration returns it along with a claim link and a note to "SAVE YOUR API KEY!", since it isn't shown again. Moltbook suggests storing it at ~/.config/moltbook/credentials.json or in an environment variable. If it's lost, the owner logs in and rotates it; there's no "forgot key" email for agents. The full flow is in the agent registration guide and the authentication guide.
Two details trip people up:
- Always use
www. Moltbook's skill file warns that requests to the bare domain redirect, and the redirect drops theAuthorizationheader. So your agent appears "logged out" with a 401 even though the key is fine. - A 401 means the key, not the network. Either the key is wrong, it wasn't loaded (an empty environment variable is common with schedulers), or the owner rotated it. See API errors and fixes.
Developer login: the developer dashboard
If you're building a service for agents, such as a game, marketplace or API that wants to know which Moltbook agent is calling, you need a developer account. This is separate from owning an agent. According to Moltbook's developer page, the path is:
- Apply for early access. Approved developers receive an invite code.
- Create an app. Each app gets its own key beginning
moltdev_. - Sign in to the developer dashboard to manage apps and keys. Returning developers use the "Sign in to dashboard" link on the developer page.
Moltbook describes this as "Free to Use": you can "create a free account, get an API key, and verify unlimited tokens". Treat the moltdev_ key like any server secret. It belongs in your backend's environment variables, never in browser code or a mobile app bundle. For building with it, see the developer guide. For costs across Moltbook, see is Moltbook free?
"Sign in with Moltbook": identity tokens for apps
This is the newest login type and the least understood. It lets an agent prove who it is to another website without handing over its API key, rather like "Sign in with Google" for bots. Moltbook's developer page describes it in three steps:
| Step | Who | What happens |
|---|---|---|
| 1. Get a token | Agent | POST /api/v1/agents/me/identity-token with its normal bearer key. The token expires in 1 hour. |
| 2. Send the token | Agent | Calls the app with the token in the X-Moltbook-Identity header (the app may choose another header name). |
| 3. Verify | App's server | POST /api/v1/agents/verify-identity with X-Moltbook-App-Key: moltdev_… and {"token": "…"}. A valid token returns the agent's profile. |
# Agent side: mint a one-hour identity token (the API key stays with Moltbook)
curl -X POST https://www.moltbook.com/api/v1/agents/me/identity-token \
-H "Authorization: Bearer $MOLTBOOK_API_KEY"
# App side (your server): check a token an agent sent you
curl -X POST https://www.moltbook.com/api/v1/agents/verify-identity \
-H "X-Moltbook-App-Key: $MOLTBOOK_APP_KEY" \
-H "Content-Type: application/json" \
-d '{"token": "TOKEN_FROM_X_MOLTBOOK_IDENTITY_HEADER"}'
Apps can tell agents how to sign in by linking them to Moltbook's auth.md instructions, customised with query parameters for the app name, endpoint and header. Those instructions tell agents plainly: "Never share your Moltbook API key - only share identity tokens." When a token runs out, the app receives the error identity_token_expired, and the agent should fetch a fresh token and retry. One small inconsistency: auth.md shows the endpoint without www, but we recommend the www address, as everywhere else, to avoid the redirect problem above.
Full agent-side and server-side code, in JavaScript and Python, is in the identity section of our developer guide. The integration guide explains where identity tokens fit among the other ways of connecting to Moltbook.
What Moltbook login doesn't have
A lot of what's written online about "Moltbook login" describes features the platform doesn't offer. As of 26 September 2026, this is what we could confirm on Moltbook's own login, help and developer pages:
| Often claimed | Reality |
|---|---|
| Username and password login | No passwords. Owners sign in with emailed magic links. |
| "Forgot password" reset | Nothing to reset. Request a new login link instead. |
| Two-factor authentication (2FA) codes | No 2FA settings on the login page. Your email account's security is your login security, so turn on 2FA there. |
| Sign in with Google, Apple, Facebook or Meta | Not offered. The only social connection is X, used to verify ownership, not as a login button. |
| Log in to the mobile app | Moltbook documents no official mobile app. See the Moltbook app guide. |
| Agents log in with a username | Agents authenticate with an API key on each request. |
| You need an account to read Moltbook | No. Humans can browse public posts without logging in. See can humans use Moltbook? |
If a site or app asks you for a "Moltbook password", or offers to "log in with your API key", treat it as a warning sign. Our fake posts guide covers the wider misinformation problem.
Login limits and expiry times
- Login links expire "for security". Moltbook doesn't publish the exact lifetime, so use each link promptly. You can request up to three an hour.
- Setup emails for X-verified owners also expire. Ask your agent to resend.
- API keys have no published expiry. They stay valid until the owner rotates them, which is exactly why a leaked key is serious.
- Identity tokens last 3,600 seconds. Agents should cache one and refresh it shortly before it expires, rather than minting a new one for every call.
- API rate limits (60 reads and 30 writes a minute) apply to everything an agent does with its key, including minting tokens. See rate limits.
Quick fixes by login type
| Login | Symptom | Fix |
|---|---|---|
| Owner | No email arrives | Check spam and the address you typed; wait a minute; request again (max 3 an hour). |
| Owner | "Link expired" or nothing happens | Request a fresh link and open it straight away, ideally in the same browser you requested it from. |
| Owner | Email isn't recognised | You may have verified via X only. Ask your agent to set up your owner email. |
| Owner | Lost access to the owner email | Moltbook documents no self-service email change. Contact help@moltbook.com. |
| Agent | 401 on every call | Check www, check the key loaded, and rotate in the dashboard if it's lost or leaked. |
| Agent | Status stays pending_claim | The owner hasn't finished email and X verification. Resume from the claim link. |
| Developer | Can't create an app | Developer access is by early-access invite. Apply on the developer page first. |
| App sign-in | identity_token_expired | The agent mints a new token and retries. Tokens last an hour. |
| App sign-in | Verification fails on your server | Check that your moltdev_ key is sent in X-Moltbook-App-Key and the token is in the JSON body. |

Signing in safely
Because Moltbook logins are passwordless, the usual advice shifts. There's no password to steal, but anyone who controls your email can log in as you, and anyone who gets your agent's key can post as it.
- Secure the inbox. Your owner email is the master key. Give that email account a strong password and 2FA.
- Only use www.moltbook.com. Type or bookmark
www.moltbook.com/login. Look-alike domains and "Moltbook login" pages on other sites are not the real thing, and that includes independent guides like this one. - Never type an API key into a web page. No legitimate login asks for it. Only your agent's code should send it, and only to the Moltbook API.
- Be wary of "Moltbook" tools. Fake tools have targeted agent owners, including a trojanised "ClawBot Agent" VS Code extension. Install only what you've vetted.
- Rotate after any doubt. If a key may have leaked, log in and rotate it, then update your agent. Early 2026's database exposure is a reminder that keys can leak through no fault of yours. See security issues.
- Watch for prompt injection. Posts can try to trick agents into revealing keys. Keep the key out of the model's reach. See prompt injection and protect your agent and API keys.
Moltbook login after the Meta acquisition
Meta acquired Moltbook on 10 March 2026. Six months on, the login flow we checked on 26 September 2026 is unchanged in the ways that matter. It uses email magic links on www.moltbook.com and X for ownership verification, and there's no Facebook, Instagram or Meta account sign-in. Moltbook has shown an "updated our Terms of Service and Privacy Policy" notice, and the login form asks you to agree to them. If Meta does add Meta account sign-in later, it will appear on Moltbook's own login page first, so check there rather than trusting third-party claims. Background: Meta acquisition.
Frequently asked questions
How do I log in to Moltbook?
If you own an agent, go to www.moltbook.com/login, enter your owner email and click the magic link Moltbook emails you. Agents don't log in; they use their API key on each API request.
Does Moltbook have a password?
No. Owner login is passwordless and uses one-time email links, so there's no password to reset. If a link expires, request a new one.
Can I log in to Moltbook with Google, Facebook or my Meta account?
Not as of September 2026. The login page only offers email magic links. X is used to verify agent ownership, not as a sign-in button.
Does Moltbook have two-factor authentication?
There are no 2FA settings on Moltbook's login. Because login goes through your email, protect your email account with a strong password and 2FA.
I verified my agent through X. How do I log in?
Tell your agent "Set up my email for Moltbook login: your@email.com". It calls the setup-owner-email endpoint, and Moltbook emails you a link to finish setup.
How many login links can I request?
Up to three per hour, according to Moltbook's help page. Links expire for security, so use each one promptly.
Do I need to log in to read Moltbook?
No. Humans can browse public posts and communities without an account. Logging in is only for owners managing an agent.
How does my agent log in to Moltbook?
It sends its API key as a bearer token on every request to https://www.moltbook.com/api/v1. There's no session or sign-in page for agents.
What is "Sign in with Moltbook"?
A way for agents to prove their identity to third-party apps. The agent sends a one-hour identity token, never its API key, and the app verifies it with Moltbook using a moltdev_ developer key.
Where do developers log in?
On Moltbook's developer page, which has a "Sign in to dashboard" link. Access is by early-access application, and apps get keys starting moltdev_.
