ChatGPT login loop won't let me sign in
You enter your email, click "Continue", authenticate — and then land right back at the login screen. It's not your password, not your internet, and refreshing doesn't help. This login loop affects both free and Plus users across all browsers and happens when OpenAI's session management conflicts with your browser state or account verification.
What's actually happening
The login loop occurs when ChatGPT can't establish or maintain your session cookie after authentication. You're successfully proving who you are — OpenAI's servers recognise your credentials — but something prevents the session token from sticking in your browser. The page reloads, finds no valid session, and dumps you back at the login screen.
This usually stems from three specific causes. First, your browser is blocking third-party cookies or running privacy settings that prevent chatgpt.com from storing session data. Second, cached authentication data is corrupted — your browser has outdated session information that conflicts with OpenAI's current requirements. Third, your account has a verification flag that requires additional confirmation before allowing access, but the system isn't surfacing the verification prompt correctly.
The loop is most common after password changes, when switching between work and personal accounts, or during OpenAI infrastructure updates that change how sessions are validated.
How to fix it
1. Clear ChatGPT's site data completely
Open your browser settings and navigate to Privacy or Cookies. Find "chatgpt.com" specifically — not just general browsing data — and delete all cookies and site data. In Chrome, go to Settings > Privacy and security > Cookies and other site data > See all site data, search "chatgpt", and click "Remove all shown". In Firefox, Options > Privacy & Security > Cookies and Site Data > Manage Data, search "chatgpt.com", remove all entries. In Safari, Preferences > Privacy > Manage Website Data, find chatgpt.com, remove it.
After clearing, close all ChatGPT tabs completely. Open a new incognito or private window, go to chatgpt.com, and try logging in fresh.
2. Check cookie settings
Go to your browser's cookie settings. ChatGPT requires third-party cookies to maintain sessions across OpenAI's authentication domains. In Chrome, Settings > Privacy and security > Third-party cookies must be set to "Allow third-party cookies" or add "[*.]openai.com" and "[*.]chatgpt.com" as allowed sites. In Firefox, disable Enhanced Tracking Protection for chatgpt.com by clicking the shield icon in the address bar and toggling it off.
If you use browser extensions like Privacy Badger, Cookie AutoDelete, or any ad blocker, temporarily disable them and try logging in.
3. Try a different browser
Download a fresh browser you don't normally use — Chrome, Firefox, Edge, or Brave. Don't sign into any accounts or install extensions. Go directly to chatgpt.com and log in. If this works, your primary browser has a configuration issue. You can either keep using the new browser for ChatGPT or systematically re-enable extensions in your main browser to find the culprit.
4. Verify your email
Check your email inbox for messages from OpenAI within the last 48 hours. Look for subject lines containing "Verify your email" or "Action required". If you find one, click the verification link, wait for confirmation, then try logging in. If the email link is expired, go to contact OpenAI support and request a fresh verification email with your registered address.
5. Use the mobile app
Download the official ChatGPT app from the App Store or Google Play. Log in through the app. If this succeeds, your account is fine — the issue is browser-specific. You can keep using the app while troubleshooting your browser setup.
If that doesn't work
The loop might indicate account-level issues requiring OpenAI intervention. Visit help.openai.com/en/articles/6614161 (their login troubleshooting page) and submit a support request. Include your exact registered email address, the browser and version you're using, and specify "login loop after authentication — returns to login screen". Screenshot the loop happening if possible. Attach any error codes that briefly appear in the URL or on screen.
Support typically responds within 2-3 business days for login issues. If you're a ChatGPT Plus subscriber, mention your subscription status — they prioritise paying accounts. While waiting, you can access ChatGPT through the mobile app or try the API playground at platform.openai.com if you need immediate access.
Questions people actually ask
Q: Will clearing cookies delete my ChatGPT conversation history?
A: No. Your conversations are stored on OpenAI's servers, not in browser cookies. Clearing site data only removes local session tokens — your chat history remains intact under your account.
Q: Why does incognito mode work when regular browsing doesn't?
A: Incognito bypasses cached data and most extensions. If it works, something in your regular browser profile — cached cookies, an extension, or privacy settings — is blocking session establishment.
Q: Does this mean my account is banned?
A: No. Account bans show a specific error message stating your access has been terminated. A login loop means authentication succeeds but session creation fails — completely different issue. See ChatGPT not working for ban-specific symptoms.
What to remember
- Clear chatgpt.com site data specifically, not just general browser cache
- Third-party cookies must be enabled for OpenAI domains
- Incognito mode isolates the problem — if it works there, your main browser profile needs fixing
- Check email for verification requests sent in the last 48 hours
- The mobile app bypasses browser issues entirely and proves your account works
