ChatGPT login loop won't let me in

You enter your email and password, click "Continue," and ChatGPT sends you right back to the login screen. No error message, no explanation — just an endless loop that keeps you locked out of your account.

What's actually happening

The login loop happens when ChatGPT's authentication system can't complete the verification process. Your browser receives session cookies from OpenAI's servers, but something blocks them from sticking — so each login attempt starts fresh like you never logged in at all.

This affects both chatgpt.com and the mobile apps. The most common trigger is browser cache corruption, where old authentication data conflicts with new login attempts. Safari users on Mac see this more often after macOS updates, while Chrome users hit it after installing certain extensions. If you're using a VPN, corporate network, or privacy-focused browser settings, you're running blocking cookies without realising it.

Sometimes the loop appears after changing your password or switching devices. OpenAI's system sends a verification email, you click the link, authenticate successfully — then get dumped back at login anyway because the session never actually writes to your browser.

How to fix it

1. Clear your browser data completely

Open Chrome settings > Privacy and security > Clear browsing data. Select "All time" as the time range. Tick "Cookies and other site data" and "Cached images and files." Click "Clear data." For Safari, go to Settings > Privacy > Manage Website Data > Remove All. For Firefox, Settings > Privacy & Security > Cookies and Site Data > Clear Data.

2. Disable all browser extensions temporarily

Type `chrome://extensions` in Chrome's address bar and toggle off every extension, especially ad blockers, privacy tools, and VPN extensions. Try logging in at chatgpt.com. If it works, turn extensions back on one at a time to find the culprit. Privacy Badger, uBlock Origin, and Ghostery frequently block OpenAI's authentication cookies.

3. Check your VPN and network settings

Turn off any VPN completely — not just disconnect, actually quit the app. Some VPNs leave DNS routing active even when "disconnected." If you're on a work or school network, their firewall might block authentication domains. Try switching to mobile data or a different WiFi network.

4. Try incognito/private browsing

Open an incognito window (Ctrl+Shift+N in Chrome, Command+Shift+N in Safari). Go to chatgpt.com and log in. If this works, the problem is definitely cached data or an extension in your normal browser. You'll need to clear everything and reset your browser settings.

5. Use a different browser entirely

Download a browser you've never used for ChatGPT — if you normally use Chrome, try Firefox or Edge. This isolates whether the problem is account-related or browser-related. If a fresh browser works immediately, your main browser has corrupted authentication data that even clearing cache didn't remove.

6. Reset your password

Go to chatgpt.com, click "Forgot password," enter your email, and follow the reset link. This forces OpenAI to issue completely new authentication tokens. After resetting, clear your browser data again before attempting to log in with the new password.

If none of these work, you're probably dealing with an account issue beyond login troubleshooting — possibly a suspended account or authentication system bug on OpenAI's end.

If that doesn't work

Email support@openai.com with "Login loop at chatgpt.com" in the subject line. Include your account email, browser name and version, whether you're using a VPN, and exactly what happens when you try to log in. Specify if you can log in on mobile but not desktop, or vice versa. OpenAI typically responds within 2-3 business days for login issues.

Check platform.openai.com/account — if you can access your API account but not ChatGPT, that confirms the problem is session-handling specific to chatgpt.com, not account suspension.

Questions people actually ask

Q: Does clearing cookies log me out of everything?

A: Yes — you'll need to re-enter passwords for all websites. Export your passwords first through your browser's password manager if you don't remember them all.

Q: Can I fix this on mobile?

A: Uninstall the ChatGPT app completely, restart your phone, reinstall from the App Store or Google Play, then try logging in. If the loop persists, it's an account-level issue.

Q: Will I lose my chat history?

A: No — your conversations are stored on OpenAI's servers, not your browser. Once you successfully log back in, everything reappears.

Q: How long does the login loop last?

A: It doesn't resolve on its own. You must manually clear browser data or fix whatever's blocking authentication cookies.

What to remember

  • Clear browser cache and cookies for "All time" — partial clears don't work
  • Turn off every browser extension, especially privacy and ad-blocking tools
  • Try a completely different browser or incognito mode to isolate the cause
  • VPNs and corporate networks frequently block OpenAI's authentication domains
  • If nothing works, contact OpenAI support with specific details about your setup
