ChatGPT login stuck in loop keeps redirecting

You click login, enter your credentials, and ChatGPT immediately sends you back to the login page — over and over. This redirect loop hits people across browsers, devices and account types, turning a simple login into an endless cycle.

What's actually happening

The redirect loop typically starts with a broken authentication handshake between your browser and OpenAI's servers. You'll see `chatgpt.com/auth/login` flash in your address bar, followed by a redirect to the main page, then straight back to login again. Sometimes you'll briefly glimpse the ChatGPT interface before getting kicked out.

This happens when your browser can't store or retrieve the authentication token OpenAI uses to verify your session. Third-party cookies, strict privacy settings, or cached credentials from a previous failed login attempt create the loop. OpenAI's authentication system expects certain browser storage permissions — when those fail, it treats every login as invalid and sends you right back to square one.

The problem appears most frequently in Safari with "Prevent cross-site tracking" enabled, Firefox with Enhanced Tracking Protection set to Strict, and any browser using privacy-focused extensions like Privacy Badger or uBlock Origin in aggressive modes.

How to fix it

1. Clear ChatGPT-specific site data

Open your browser settings and find the option to clear data for a single site. In Chrome, click the lock icon left of `chatgpt.com` in your address bar, select "Site settings", then "Clear data". In Firefox, go to Settings → Privacy & Security → Cookies and Site Data → Manage Data, search for `chatgpt.com` and `auth0.openai.com`, then remove both. In Safari, go to Preferences → Privacy → Manage Website Data, find both domains and remove them.

2. Enable third-party cookies for OpenAI domains

ChatGPT's authentication uses Auth0, which requires cross-site cookie storage. In Chrome, go to Settings → Privacy and security → Third-party cookies → "Allow third-party cookies" and add `[*.]chatgpt.com` and `[*.]auth0.openai.com` to allowed sites. In Firefox, set Enhanced Tracking Protection to Standard (Settings → Privacy & Security). In Safari, disable "Prevent cross-site tracking" temporarily (Preferences → Privacy).

3. Disable browser extensions

Open an incognito or private window where extensions typically don't run. Try logging in there. If it works, you've identified the culprit. Common offenders: Privacy Badger, Ghostery, uBlock Origin with default filter lists, and any VPN browser extensions. Disable them one by one to find which blocks the authentication flow.

4. Try the direct login URL

Navigate directly to `https://chatgpt.com/auth/login` instead of clicking login from the homepage. Some users report this bypasses the redirect logic that creates the loop.

5. Switch networks

Corporate, school and public WiFi networks often inject headers or filter traffic in ways that break OAuth flows. Switch to mobile data or a different network. If login works there, your network is blocking part of the authentication process.

If you've tried all five steps and you're still looping, you might have an account-level issue. Check if you can log in to ChatGPT using the mobile app — if that works but the browser doesn't, your account is fine and the problem is definitely browser-side.

If that doesn't work

The loop sometimes indicates a suspended or flagged account. Try logging into `https://platform.openai.com/account` with the same credentials. If you see an error message there, contact OpenAI support with your email address and the exact error text. Include a screenshot of the redirect loop showing the URL changes.

Tell support which browser version you're using, whether incognito mode worked, and what you see in your browser's developer console (press F12, click Console tab, screenshot any red errors during login). Most authentication issues get responses within 24-48 hours.

Questions people actually ask

Q: Does clearing cookies log me out of everything?

A: Clearing site-specific data only affects ChatGPT. Use the per-site clearing method in step 1 instead of your browser's "Clear all browsing data" option to avoid logging out of other services.

Q: Will allowing third-party cookies make me less secure?

A: Allowing them only for `chatgpt.com` and `auth0.openai.com` doesn't significantly impact your overall privacy. You're creating specific exceptions, not disabling protection everywhere.

Q: My company VPN blocks third-party cookies — what now?

A: Use the ChatGPT mobile app or ask your IT department to whitelist `auth0.openai.com` in your VPN's cookie policy. Corporate VPNs often block OAuth flows by default.

What to remember

  • Clear site data for both `chatgpt.com` and `auth0.openai.com` before trying anything else
  • Third-party cookies must be enabled specifically for Auth0 domains
  • Incognito mode tells you if extensions are causing the problem
  • Network restrictions often create redirect loops on corporate or school WiFi
  • If the mobile app works but browsers don't, your account isn't the issue
