ChatGPT login loop won't let me in

You enter your email and password, ChatGPT redirects you, then kicks you straight back to the login screen. You're stuck in an endless loop and can't access your account — even though your credentials are correct.

What's actually happening

The login loop happens when ChatGPT's session management gets confused between your browser and OpenAI's authentication servers. You're successfully authenticating, but the session token either isn't saving to your browser or isn't being recognised when you're redirected back to chatgpt.com.

This typically stems from three causes: your browser blocking third-party cookies (which OpenAI needs to maintain your session), cached authentication data conflicting with new login attempts, or browser extensions interfering with the redirect chain. The loop affects both free and Plus users equally — your subscription status doesn't matter here.

If you see the login page flash briefly before looping back, that's your browser failing to store the session cookie. If you see "Too many redirects" or a blank page between loops, that's cached redirect instructions pointing to expired URLs.

How to fix it

1. Clear your browser's cache and cookies specifically for OpenAI domains

In Chrome: Settings → Privacy and security → Clear browsing data → Choose "Cookies and other site data" and "Cached images and files" → Time range: All time → Paste `chatgpt.com` and `auth0.openai.com` into the search if your browser allows site-specific clearing.

In Safari: Preferences → Privacy → Manage Website Data → Search for "openai" and "auth0" → Remove all entries.

In Firefox: Settings → Privacy & Security → Cookies and Site Data → Manage Data → Search "openai" → Remove Selected.

Close the browser completely, reopen it, and try logging in again.

2. Check your cookie settings aren't blocking authentication

Go to your browser's Privacy settings and confirm "Block all cookies" is turned off. ChatGPT specifically needs cookies from `auth0.openai.com` to complete login. You can allow cookies just for OpenAI domains if you run strict privacy settings elsewhere.

In Chrome: Settings → Privacy and security → Third-party cookies → Select "Allow third-party cookies" or add `[*.]openai.com` and `[*.]auth0.openai.com` to allowed sites.

3. Disable browser extensions temporarily

Ad blockers, privacy tools (Privacy Badger, uBlock Origin, Ghostery), and VPN extensions routinely break login flows. Open an incognito or private browsing window — this automatically disables most extensions. Try logging in there. If it works, you've confirmed an extension is the culprit.

Re-enable extensions one by one to identify which one breaks login, then whitelist `*.openai.com` in that extension's settings.

4. Try a different browser or device

If you're stuck in Chrome, open Firefox or Safari and attempt login there. If you're on a work computer, try your phone's browser. A fresh environment often bypasses whatever's causing the loop on your primary setup — and confirms whether it's browser-specific or account-specific.

5. Check if you're using the right authentication method

If you originally signed up with Google, Microsoft, or Apple login, don't try entering an email and password — OpenAI never created password credentials for your account. Click "Continue with Google" (or whichever service you used) instead. Mixing authentication methods triggers loops because the system can't match your login attempt to an existing account method.

If that doesn't work

Wait 30 minutes and try again — OpenAI's authentication servers occasionally glitch during high traffic and resolve themselves. If the loop persists beyond two hours, contact OpenAI support at help.openai.com/messages. Include this information:

  • The exact error message (if any) or "infinite login loop"
  • Which browser and version you're using
  • Whether incognito mode worked or failed
  • Your account email address
  • Whether you're on a corporate network or VPN

Response time typically runs 24-48 hours. Don't create a second account to report the issue — that can complicate recovery if your original account has subscription data.

Questions people actually ask

Q: Will I lose my chat history if I clear cookies?

A: No. Your chat history lives on OpenAI's servers, not in browser cookies. Clearing cookies only removes your local login session — you'll see all your conversations once you successfully log back in.

Q: Does this mean my account is banned?

A: No. Banned accounts show a red error message stating "Your account has been deactivated" — you wouldn't see a login loop. If you're worried about your account status, check our guide on how to tell if you're banned.

Q: Can I fix this on mobile?

A: Yes. Clear the ChatGPT app cache (iOS: delete and reinstall the app; Android: Settings → Apps → ChatGPT → Storage → Clear cache) or use your mobile browser instead of the app.

What to remember

  • Login loops are browser session problems, not account problems
  • Clear OpenAI-specific cookies and cache first — generic clearing often misses authentication domains
  • Try incognito mode to instantly test if extensions are interfering
  • Use the same authentication method (Google/Microsoft/Apple) you originally signed up with
  • If nothing works after two hours, contact support with specific browser details
