Muse AI Login: How to Sign In to Muse (App, Web, WhatsApp)
How to sign in to Muse, Meta's personal AI agent — Meta Account login in the app, auth.muse.ai on the web, and WhatsApp access. Plus launch-day login fixes.
Muse signs in with a Meta account — the same login you use for Facebook, Instagram and WhatsApp. There is no separate "Muse account" to create. Here's where to sign in on each platform, and what to do if the login screen gives you trouble.
Where Muse asks you to log in
| Surface | Login method |
|---|---|
| Muse app (iOS / Android) | Meta account, in-app sign-in |
| Web | muse.ai → redirects to auth.muse.ai (Meta's authentication domain) |
| No separate login — Muse works through your WhatsApp account |
If you're ever unsure whether a Muse login page is real, check the address: Meta's official web login lives on auth.muse.ai. Phishing pages love AI launches, so never enter your Meta password anywhere else.
How to sign in to the Muse app
- Install Muse from Meta from the App Store (iOS 18+) or Google Play.
- Open the app and tap sign in.
- Enter your Meta account credentials — the same email or phone and password you use for Facebook or Instagram.
- Follow setup: TechCrunch reports Muse asks for a payment card during signup (tied to agent purchases, not the free tier). Apple's listing rates the app 17+, and press coverage describes Muse as intended for adults 18+.
- Connect apps (email, calendar, payments) only as you're ready — each connection asks how much access Muse gets.
How to sign in on the web
Go to muse.ai in a browser. The site redirects to auth.muse.ai, where you sign in with your Meta account. The web version is part of the US rollout — if it shows a waitlist-style block or won't load your account, Muse may not be available to you yet (see Muse availability).
Using Muse without logging in at all
In the US, you can use Muse directly in WhatsApp — Meta describes it as working "just like messaging another person." There's no separate Muse login: it rides on your WhatsApp account. The WhatsApp version skips the app's feed and ideas features but handles core conversations and tasks. Details: Muse on WhatsApp.
Common Muse login problems
Launch week has been bumpy for some users. These are the reported issues and what helps:
- "This account needs permission to view this page" — reported by early users on launch day. Meta hasn't published an official fix. Things to try: fully close and reopen the app, confirm you're using the right Meta account, then try muse.ai in a browser to see whether the web login works for your account.
- App loads but content stays blank / won't hydrate — also reported at launch. Update to the latest app version, force-close, and reopen. If it persists, wait a few hours; rollout glitches have been resolving on their own.
- "Muse isn't available in your country" — that's not a bug. Muse is rolling out in the US only as of September 9, 2026. There's no official waitlist. Status: Muse availability.
- I'm in the US and still don't see Muse — also not a login bug. "Rolling out" means access appears in stages even inside the US; some American users are still waiting days after launch. There's no invite code or waitlist to join — keep the app updated and retry, or check muse.ai periodically.
- Wrong Meta account — if your Facebook and Instagram use different logins, confirm which one is your primary Meta account at meta.com before signing in.
- Password problems — Muse uses your Meta account password. Reset it through Meta's official account center, not through any "Muse support" page (none exists yet).
Is my login safe?
Your Muse session connects to your own Muse Secure VM — a dedicated cloud environment where connected-app credentials are stored so the agent can use them without seeing them. Meta's security team publishes details at its safety post, and security researchers can reach muse-security@meta.com. Our Muse privacy guide covers every control in plain English.
Tips
- Sign in on one surface first (app or web), confirm it works, then add WhatsApp.
- Use a strong, unique Meta account password — Muse can touch your email, calendar and payments.
- Review the approval and privacy settings right after your first login; our prompt generator also bakes approval rules into every task you give it.
FAQ
- Can I stay logged in on multiple devices? Yes — app, web and WhatsApp sessions coexist; your tasks and memory stay in sync through your VM.
- Is there a "Muse business login"? No. Muse has no separate business tier or login as of September 9, 2026.
- Does Muse work without a Facebook account? It requires a Meta account, which you can create without an active Facebook profile — but WhatsApp access still needs a WhatsApp account.
- Where do I report a login security issue? Security researchers:
muse-security@meta.comper Meta's security post. Everyone else: watch for a Muse help center — as of today, Meta hasn't published one.

Frequently Asked Questions
Do I need a Meta account to use Muse?
Yes. Muse signs in with a Meta account — the same account family used for Facebook, Instagram and WhatsApp. The web app logs in through auth.muse.ai, Meta's own authentication domain.
Why does Muse ask for a payment card at signup?
TechCrunch's launch report says Muse requires a payment card to get started, likely because the agent can make purchases through Link built by Stripe. Purchases are separate from the free tier, and Muse is designed to ask your approval before buying anything.
Is there a Muse login problem right now?
Some launch-day users reported sign-in errors and pages that wouldn't load in the first days after release. If you hit "This account needs permission to view this page" or a blank screen, update the app, sign out and back in, or try muse.ai in a browser.
Can I log in to Muse with WhatsApp only?
Yes — in regions where Muse has rolled out, talking to Muse in WhatsApp works without installing the app. WhatsApp uses your existing account, so there's no separate Muse login step there.
