ChatGPT login loop won't let me in
You click "Log in", enter your credentials, and ChatGPT just dumps you right back at the login screen. No error message, no explanation — just an endless loop that won't let you access your account.
ChatGPT login loop won't let me in
You click "Log in", enter your credentials, and ChatGPT just dumps you right back at the login screen. No error message, no explanation — just an endless loop that won't let you access your account.
What's actually happening
This login loop happens when ChatGPT's authentication system fails to create or maintain your session cookie. Your credentials are correct, OpenAI's servers verify them, but something breaks in the handshake between your browser and the platform. You're stuck in limbo — authenticated but never actually logged in.
The most common trigger is corrupted browser data. When ChatGPT sets a session cookie, your browser stores it with specific parameters. If that cookie gets corrupted, blocks itself, or conflicts with existing data, the authentication completes but the session never starts. You see the login page again because ChatGPT thinks you never logged in at all.
Browser extensions cause this constantly. Ad blockers, privacy tools, and VPNs often interfere with the authentication cookies ChatGPT needs. Even legitimate security extensions can block the cross-site requests that complete the login process.
How to fix it
1. Clear ChatGPT's site data completely
Open your browser settings and find the option to clear browsing data. In Chrome, go to Settings > Privacy and security > Clear browsing data. Select "Advanced" and choose "All time" as the time range. Check only "Cookies and other site data" and "Cached images and files". Click Clear data.
For Firefox: Settings > Privacy & Security > Cookies and Site Data > Clear Data. For Safari: Preferences > Privacy > Manage Website Data, search for "openai.com" and "chatgpt.com", then Remove.
2. Disable all extensions temporarily
Open an incognito or private window. Most browsers disable extensions by default in these windows. Try logging in at chatgpt.com. If it works, an extension is blocking your session cookies.
To identify which one, re-enable extensions one at a time in regular mode until the loop returns. The most common culprits: Privacy Badger, uBlock Origin, Ghostery, any VPN extension, and Cookie AutoDelete.
3. Check your system time
Click your computer's clock. Verify it matches the current time in your timezone. Authentication tokens use timestamps — if your system clock is off by more than a few minutes, session cookies fail validation. Set your time to update automatically through your operating system settings.
4. Try a different browser
Download a fresh browser you don't normally use. Chrome, Firefox, Edge, or Brave all work. Don't import settings or extensions. Go directly to chatgpt.com and log in. If this works, your primary browser has persistent data blocking the session.
5. Disable any network-level blocking
If you're using a VPN, Pi-hole, or DNS-level ad blocker (like NextDNS or AdGuard DNS), disable it temporarily. These tools block tracking domains that ChatGPT's login flow depends on. The authentication process uses openai.com, chatgpt.com, and several CDN domains — blocking any of them breaks the loop.
If that doesn't work
Your account might have a security flag preventing new sessions. This happens after suspicious login attempts or if OpenAI detected unusual activity. You won't see an error — just the loop.
Visit how to contact OpenAI support and submit a ticket with these details: your email address, the exact time you tried logging in (including timezone), and whether you recently changed your password or location. Include your browser name and version, like "Chrome 131.0.6778.109 on Windows 11".
Response times average 2-4 business days for login issues. You won't get an immediate fix, but they can check if your account has authentication restrictions.

Questions people actually ask
Q: Will clearing cookies delete my chat history?
A: No. Your conversations live on OpenAI's servers, tied to your account. Clearing cookies only removes local browser data — you'll see all your chats once you successfully log in.
Q: The loop happens on every device I try. Is my account banned?
A: Probably not. Banned accounts show an explicit error message. A loop across all devices usually means a VPN or network-level blocker is following you, or your account has a temporary security hold. Check if you're using the same VPN or DNS service everywhere.
Q: I can log in on mobile but not desktop — why?
A: Desktop browsers store more persistent data and run more extensions. Your mobile app uses a different authentication flow that bypasses whatever's blocking your desktop browser. This confirms it's a local browser issue, not an account problem.
What to remember
- Clear all cookies and cache for chatgpt.com and openai.com specifically
- Test in incognito mode with zero extensions to isolate the cause
- Verify your system clock shows the correct time automatically
- Disable VPNs and network-level blockers during login
- Account-level blocks usually show error messages, not silent loops
