ChatGPT login loop won't let me in

You enter your email and password, click sign in, and land right back at the login page. Again. And again. The login loop is one of the most frustrating ChatGPT access issues, and it usually points to cookie problems, browser cache conflicts, or session authentication failures on OpenAI's end.

What's actually happening

When you're stuck in a login loop, your browser and OpenAI's servers aren't maintaining a proper session. You authenticate successfully — your credentials work — but the session cookie that tells ChatGPT "this user is logged in" either isn't saving, isn't being read correctly, or is immediately invalidating.

This happens most often after browser updates, when using privacy-focused settings that block third-party cookies, or when ChatGPT's authentication service (auth0.openai.com) hits a temporary glitch. You'll see the login page at chatgpt.com reload, sometimes with no error message at all. Occasionally you'll get "Something went wrong" or "Unable to load site" before being kicked back to the login screen.

The loop affects both free and Plus users equally, and it doesn't mean your account is banned or suspended. Your credentials are fine — the problem is session management.

How to fix it

1. Clear site data for ChatGPT specifically

Don't just clear your entire browser history. Target ChatGPT's stored data:

  • Chrome/Edge: Go to chatgpt.com, click the lock icon in the address bar, select "Cookies and site data", click "Manage on-device site data", remove all entries for chatgpt.com and auth0.openai.com, then click Done
  • Firefox: Settings > Privacy & Security > Cookies and Site Data > Manage Data, search for "openai", remove all entries
  • Safari: Preferences > Privacy > Manage Website Data, search "openai", remove all

After clearing, close the browser completely (not just the tab) and reopen it.

2. Disable browser extensions temporarily

Ad blockers, privacy extensions (Privacy Badger, uBlock Origin, Ghostery), and VPNs frequently interfere with authentication cookies. Open an incognito/private window and try logging in there. If it works, you've confirmed an extension conflict. Disable extensions one by one on your normal browser to find the culprit, or add chatgpt.com to your extension's allowlist.

3. Check cookie settings

ChatGPT requires first-party cookies enabled. Check your browser:

  • Chrome: Settings > Privacy and security > Cookies and other site data — select "Allow all cookies" or "Block third-party cookies" (not "Block all cookies")
  • Firefox: Settings > Privacy & Security — set to "Standard" not "Strict"
  • Safari: Preferences > Privacy — uncheck "Block all cookies"

4. Try a different browser

If you're using Brave, Arc, or another privacy-focused browser with aggressive defaults, switch to Chrome, Firefox, or Edge temporarily. This isolates whether your browser's privacy features are the problem.

5. Verify your network

Some corporate networks, school WiFi, or public hotspots block authentication domains. Try logging in on your phone using mobile data instead of WiFi. If that works, your network is filtering OpenAI's login servers. You'll need to contact your IT department or use a different network.

If that doesn't work

If the login loop persists after clearing cookies and trying incognito mode, the issue is likely on OpenAI's end. Check status.openai.com for current service disruptions affecting authentication. Authentication outages are listed under "API" or "ChatGPT" services.

When contacting OpenAI support, include:

  • Your exact browser name and version (find this in browser settings > About)
  • Whether incognito/private browsing works
  • The exact URL you land on after clicking sign in
  • Any error codes or messages, even brief ones
  • Whether you're using a VPN or work network

For detailed instructions on how to contact OpenAI support, you'll want to submit a request through help.openai.com and expect a response within 2-3 business days for login issues.

Questions people actually ask

Q: Does the login loop mean my account is banned?

A: No. If you were banned, you'd see a specific error message stating your account has been deactivated. A login loop is a technical issue, not an account suspension. Learn more about what happens when you can't log in to ChatGPT.

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

A: Incognito disables extensions and uses default cookie settings. This means either a browser extension or your custom privacy settings are blocking the authentication cookie in normal mode.

Q: I cleared everything and it still loops. Now what?

A: Try a completely different device — your phone, a different computer, anything. If the loop persists across all devices and networks, your account has a server-side session issue that only OpenAI support can resolve.

What to remember

  • Clear cookies specifically for chatgpt.com and auth0.openai.com, not your whole browser
  • Test in incognito mode first to rule out extensions
  • Make sure first-party cookies are enabled in browser settings
  • Try mobile data instead of WiFi to check for network blocks
  • If nothing works across multiple devices, submit a support ticket with your browser version and exact error behaviour
