ChatGPT login loop won't let me sign in

You click "Log in", enter your credentials, hit submit — and you're right back at the login screen. No error message, no explanation, just an endless loop that keeps you locked out of ChatGPT.

This login loop affects users across all browsers and often happens after password resets, account security checks, or when OpenAI flags unusual login patterns. The good news: it's almost always fixable on your end.

What's actually happening

The login loop typically means your browser can't complete the authentication handshake with OpenAI's servers. When you submit credentials, OpenAI's system verifies them and tries to set a session cookie. If that cookie fails to save — or gets immediately cleared — the system thinks you never logged in and boots you back to the start.

This happens most often when browser security settings block third-party cookies, when extensions interfere with authentication scripts, or when cached login data conflicts with new credentials. Sometimes OpenAI's systems flag your account for additional verification but the verification step doesn't load, creating an infinite redirect.

You might see the page flash briefly to a loading state or even show "Redirecting..." before dumping you back at the login screen. No error code appears because technically nothing's broken — the authentication just can't complete the cycle.

How to fix it

1. Clear ChatGPT cookies and cache

Go to your browser settings and clear browsing data for the last 24 hours. Select "Cookies" and "Cached images and files" — don't just clear history. In Chrome, go to Settings > Privacy and security > Clear browsing data. In Firefox, Preferences > Privacy & Security > Cookies and Site Data > Clear Data. Make sure you include `chat.openai.com`, `openai.com`, and `auth0.openai.com`.

2. Enable cookies for OpenAI domains

Check that your browser allows cookies. In Chrome: Settings > Privacy and security > Cookies and other site data > ensure "Allow all cookies" is selected or add `[*.]openai.com` to allowed sites. In Firefox: Preferences > Privacy & Security > set "Standard" or add exceptions for OpenAI domains. Safari users: Preferences > Privacy > uncheck "Block all cookies".

3. Disable extensions temporarily

Browser extensions — especially ad blockers, privacy tools and VPNs — can block authentication scripts. Open an incognito or private window (which disables most extensions by default) and try logging in at `https://chatgpt.com`. If it works there, the culprit is an extension. Disable them one by one in normal mode to find which one's causing trouble.

4. Try a different browser

If you're stuck in Chrome, open Firefox, Safari or Edge and attempt login there. If it works, your original browser has a configuration problem. If the loop happens everywhere, your account needs attention — proceed to step 5.

5. Check for security emails from OpenAI

Open your email and search for messages from `noreply@openai.com` or `no-reply@tm.openai.com`. OpenAI sometimes requires you to verify login attempts from new devices or locations. Click any verification links before trying to log in again. These emails expire after a few hours, so request a new one if needed.

If you changed your password recently and immediately hit a login loop, wait 10 minutes before trying again — OpenAI's systems need time to propagate password changes across all authentication servers.

If that doesn't work

Head to `https://platform.openai.com` and try logging in there instead of chatgpt.com. If you can access the platform dashboard, your ChatGPT-specific session has an issue — log out completely from platform.openai.com, then try ChatGPT again.

Still looping? Contact OpenAI support through `help.openai.com/en/articles/6614161`. Include your exact browser version, operating system, and whether you can log in from mobile devices. Mention if you recently reset your password, changed security settings, or received any account security emails. OpenAI typically responds within 2-3 business days for login issues.

If you suspect your account is banned or restricted, check how to appeal an OpenAI ban — though banned accounts usually show an error message rather than a silent loop.

Questions people actually ask

Q: Does clearing cookies log me out of everything?

A: Yes, you'll need to log back into other sites. Only clear data for the last 24 hours to minimise disruption, or clear only OpenAI-specific cookies if your browser allows site-specific clearing.

Q: Why does incognito mode work but normal browsing doesn't?

A: Incognito disables extensions and uses fresh cookie settings. This confirms a browser extension or corrupted cookie is blocking authentication. Disable extensions in your normal browser to fix it permanently.

Q: Can VPNs cause login loops?

A: Absolutely. OpenAI blocks some VPN IP ranges or requires extra verification when you connect from different countries. Try disconnecting your VPN before logging in.

What to remember

  • Clear cookies specifically for openai.com domains, not just general browsing history
  • Test in incognito mode to isolate extension conflicts
  • Allow cookies for `[*.]openai.com` in browser privacy settings
  • Check email for verification requests from OpenAI before repeatedly attempting login
  • Wait 10 minutes after password resets before trying to log back in
