ChatGPT login loop keeps happening

You enter your email and password, ChatGPT seems to accept them, then bounces you straight back to the login screen. This login loop hits both free and Plus users, especially after browser updates or when switching between devices.

What's actually happening

The login loop usually means your browser isn't storing the authentication cookie ChatGPT needs to keep you signed in. After you successfully authenticate, OpenAI's servers send back a session token. If your browser blocks or immediately deletes this cookie, the system can't verify who you are on the next page load — so it redirects you back to login.

This happens most often when you've got strict privacy settings enabled, third-party cookies blocked, or browser extensions interfering with authentication. Sometimes it's Safari's Intelligent Tracking Prevention doing exactly what it's designed to do — blocking cross-site tracking, which unfortunately includes some legitimate session cookies.

You might also hit this loop if OpenAI's authentication service detects something unusual about your login attempt: rapid-fire login attempts, VPN server changes mid-session, or cached credentials that don't match current account status. The system doesn't show you a specific error — it just loops.

How to fix it

1. Clear ChatGPT cookies and cache

In Chrome: Settings → Privacy and security → Clear browsing data → choose "Cookies and other site data" and "Cached images and files" → set time range to "Last 7 days" → tick only chatgpt.com and openai.com → Clear data.

In Safari: Preferences → Privacy → Manage Website Data → search for "chatgpt" and "openai" → Remove → Done.

Try logging in immediately after clearing. If the loop continues, move to step 2.

2. Enable third-party cookies temporarily

In Chrome: Settings → Privacy and security → Third-party cookies → select "Allow third-party cookies." You can restrict this again after login succeeds.

In Firefox: Settings → Privacy & Security → Enhanced Tracking Protection → Custom → uncheck "Cookies" → try login → re-enable after.

Safari users need to disable "Prevent cross-site tracking" under Preferences → Privacy. This is the most common culprit for Safari login loops.

3. Try incognito or private browsing

Open a private window, navigate to chatgpt.com, and attempt login. If it works here but not in your regular browser, you've confirmed that an extension or persistent setting is blocking authentication. Disable extensions one by one in your normal browser — password managers, ad blockers and privacy tools like Privacy Badger frequently interfere.

4. Switch browsers or devices

Test login on a completely different browser or the ChatGPT mobile app. If you can log in elsewhere, the problem is definitely browser-specific. If the loop persists across every browser and device, your account might have an authentication flag that needs support intervention.

5. Check for VPN or network issues

Disable your VPN temporarily and try login on your standard home or mobile network. OpenAI's system sometimes flags frequent IP changes as suspicious and refuses to complete authentication. If you must use a VPN, connect before opening ChatGPT and don't switch servers mid-session.

If that doesn't work

If you've cleared cookies, enabled third-party cookies, tested in private browsing and tried different networks without success, you need to contact OpenAI directly. Visit help.openai.com and use the chat widget to describe the issue. Include:

  • The exact browser and version you're using
  • Whether you can log in on mobile
  • Any error messages you see (even brief flashes)
  • Your account email address

Typical response time is 24-48 hours. They may ask you to try logging in from platform.openai.com instead of chatgpt.com — occasionally one domain works when the other doesn't. You can find more escalation options in our guide on how to contact OpenAI support.

Questions people actually ask

Q: Does clearing cookies log me out of everything?

A: Yes — you'll need to re-enter passwords for any sites where cookies were cleared. Only clear data for chatgpt.com and openai.com to minimize disruption.

Q: Will this affect my ChatGPT conversation history?

A: No. Your chat history is stored on OpenAI's servers, not in browser cookies. Clearing cookies only removes local authentication tokens.

Q: Can I fix this on the mobile app?

A: App login loops are less common. Try uninstalling and reinstalling the app, or use the "Continue with Google/Apple" option instead of email/password login.

What to remember

  • The login loop is almost always a cookie or browser privacy setting blocking session tokens
  • Start by clearing cookies for chatgpt.com and openai.com specifically
  • Safari users should disable "Prevent cross-site tracking" during login
  • Test in private browsing to isolate extension interference
  • If nothing works across all browsers and devices, contact support with specific details about what you've tried
