ChatGPT login loop keeps happening

You enter your email and password, ChatGPT loads for a second, then kicks you right back to the login screen. This loop can repeat endlessly, blocking access to your account even when your credentials are correct.

What's actually happening

The login loop happens when ChatGPT's authentication cookies fail to save properly in your browser. You're technically logging in successfully on OpenAI's servers, but your browser can't store the session token that proves you're authenticated. Without that token, ChatGPT's next page load doesn't recognise you're logged in, so it redirects you straight back to the login screen.

Browser privacy settings cause this most often. If you've set your browser to block third-party cookies or enabled strict tracking protection, the authentication domain can't write the session cookie it needs. Extensions like Privacy Badger, uBlock Origin in strict mode, or VPN browser plugins also interfere with the cookie handshake between chatgpt.com and auth0.openai.com.

Cached authentication data from previous sessions creates loops too. When outdated cookies conflict with fresh login attempts, your browser sends mixed signals about your authentication state. The server sees valid credentials but receives corrupt session data, triggering an endless redirect cycle.

How to fix it

1. Enable all cookies for OpenAI domains

In Chrome: Go to Settings > Privacy and security > Cookies and other site data > See all site data and permissions. Search for "openai" and "auth0". Delete everything listed. Then click "Add" under Sites that can always use cookies, and add `[*.]openai.com` and `[*.]auth0.openai.com`.

In Firefox: Open Settings > Privacy & Security > Cookies and Site Data > Manage Exceptions. Add `https://chatgpt.com` and `https://auth0.openai.com` with "Allow" permission.

In Safari: Go to Preferences > Privacy, uncheck "Prevent cross-site tracking" temporarily, then try logging in. If it works, you can re-enable the setting and add openai.com to exceptions under Manage Website Data.

2. Clear OpenAI cookies and cache completely

Don't just clear "browsing history" — that often misses authentication data. In Chrome, press Ctrl+Shift+Delete (Cmd+Shift+Delete on Mac), select "All time" as the time range, check only "Cookies" and "Cached images and files", then click Clear data. Close your browser completely and reopen it before attempting to log in to ChatGPT again.

3. Disable browser extensions temporarily

Extensions cause login loops more often than people realise. Open an incognito/private window (where most extensions are disabled by default) and try logging in at chatgpt.com. If it works, you've confirmed an extension is blocking authentication. Re-enable extensions one by one to identify the culprit — ad blockers and privacy tools are the usual suspects.

4. Try a different browser entirely

If Chrome loops endlessly, download Firefox or Edge and attempt login there. This isolates whether the issue is browser-specific configuration or an account-level problem. If a fresh browser works immediately, your primary browser has corrupted authentication settings that need deeper cleaning.

5. Check your VPN and network settings

Some VPNs and corporate firewalls block the authentication redirect that completes login. Disconnect your VPN completely, switch to a different network (like mobile hotspot), and try again. If login succeeds without VPN, configure your VPN to whitelist *.openai.com and *.auth0.openai.com domains.

If that doesn't work

When you've exhausted browser fixes and still face login loops, the issue might be account-specific. OpenAI's system occasionally flags accounts for security review, which can prevent successful authentication without showing an explicit error message.

Contact OpenAI through help.openai.com/en, click "Messages" in the bottom right, select "ChatGPT" as the product, then "Account issues". Include your exact email address, browser type and version, whether incognito mode works, and the timestamp of your last successful login. Response times average 2-4 business days currently. Check your spam folder — OpenAI's replies often land there.

Screenshot the login screen at the exact moment it loops back. Note the URL in your address bar when it happens — if you see authentication error codes in the URL parameters (like `error=access_denied`), include those in your support message.

Questions people actually ask

Q: Will deleting cookies log me out of other sites?

A: Only if you clear cookies for all sites. Use site-specific cookie deletion (searching for "openai" in your browser's cookie manager) to avoid affecting other logins.

Q: Does this mean my account is banned?

A: No. Banned accounts show an explicit error message stating the ban. Login loops are technical authentication failures, not enforcement actions. Learn more about what happens with banned accounts.

Q: Can I fix this on the ChatGPT mobile app?

A: The mobile app uses different authentication. If the website loops but the app works, that confirms browser-specific issues. Try the web fixes above.

What to remember

  • Allow cookies specifically for openai.com and auth0.openai.com domains
  • Clear all cached data for OpenAI sites, not just browsing history
  • Test in incognito mode to rule out extension conflicts
  • VPNs and strict privacy settings block the authentication handshake
  • If nothing works after 24 hours, contact OpenAI support with specific browser details
