ChatGPT login loop keeps happening
You enter your email and password, ChatGPT seems to accept them, then dumps you right back at the login screen. No error message, no explanation — just an endless loop that won't let you in.
ChatGPT login loop keeps happening
You enter your email and password, ChatGPT seems to accept them, then dumps you right back at the login screen. No error message, no explanation — just an endless loop that won't let you in.
What's actually happening
Login loops usually mean your browser can't save the authentication cookie ChatGPT needs to keep you logged in. When you sign in successfully, OpenAI's server sends your browser a session token. If your browser blocks or immediately deletes that token, ChatGPT can't verify you're authenticated — so it kicks you back to the login page.
This happens most often with aggressive privacy settings, browser extensions that block third-party cookies, or outdated cached data telling your browser to reject OpenAI's authentication. Sometimes it's your VPN or network firewall interfering with the secure connection ChatGPT needs to verify your credentials.
The loop can also trigger if you're switching between multiple accounts too quickly, or if OpenAI's authentication service temporarily flags your login as suspicious — though in those cases you'd typically see a verification challenge, not a silent loop.
How to fix it
1. Clear ChatGPT cookies and cache
In Chrome: press `Ctrl+Shift+Delete` (Windows) or `Cmd+Shift+Delete` (Mac), select "Cookies and other site data" plus "Cached images and files", change the time range to "All time", then click Clear data. In Safari: Preferences → Privacy → Manage Website Data, search for "openai.com" and "chatgpt.com", then Remove. In Firefox: Settings → Privacy & Security → Cookies and Site Data → Manage Data, search "openai", Remove Selected.
After clearing, close your browser completely and reopen it before trying to log in again.
2. Allow third-party cookies for ChatGPT
Many browsers block third-party cookies by default. In Chrome: Settings → Privacy and security → Third-party cookies, select "Allow third-party cookies" or add `[*.]openai.com` and `[*.]chatgpt.com` to the "Sites that can always use cookies" list. In Safari: Settings → Privacy, uncheck "Block all cookies" (or add exceptions for openai.com). In Firefox: Settings → Privacy & Security → Enhanced Tracking Protection, click "Manage Exceptions" and add `https://chatgpt.com`.
3. Disable browser extensions temporarily
Open an incognito or private window (extensions are usually disabled there) and try logging in. If it works, you've confirmed an extension is blocking authentication. Common culprits: Privacy Badger, uBlock Origin, Ghostery, any VPN browser extension. Disable them one by one in your normal browser to find the problem, then whitelist ChatGPT in that extension's settings.
4. Turn off your VPN
Some VPNs route traffic through servers that OpenAI's system flags as risky, triggering silent authentication failures. Disconnect your VPN completely, restart your browser, and try logging in. If that works, either keep the VPN off for ChatGPT or try a different VPN server location — US and EU servers usually work better than others.
5. Check your system date and time
Authentication tokens expire based on timestamps. If your computer's clock is wrong by more than a few minutes, the token ChatGPT issues will appear invalid. On Windows: Settings → Time & language → Date & time, turn on "Set time automatically". On Mac: System Settings → General → Date & Time, enable "Set time and date automatically".
If none of these work, you might have a broader ChatGPT login issue requiring email verification or password reset.
If that doesn't work
Try logging in on a different device or network — use your phone on cellular data, or a different computer. If that succeeds, your original device has a persistent browser or network configuration problem.
Contact OpenAI support through help.openai.com, click "Messages" at the bottom right, and include: your exact browser version (find this in your browser's About section), whether incognito mode worked, what extensions you have installed, and whether a different device succeeded. Response time is typically 2-4 business days.
As explained in how to contact OpenAI support, there's no phone number — the help centre's message system is your only option.
Questions people actually ask
Q: Does the login loop mean my account is banned?
A: No. Banned accounts show a specific "Your account has been disabled" message on the login screen. A silent loop is always a browser or network issue, not an account suspension.
Q: Why does it only happen on my work computer?
A: Corporate networks often block third-party authentication cookies or use firewalls that interfere with OpenAI's verification servers. Ask IT to whitelist `*.openai.com` and `*.auth0.com`.
Q: Will I lose my chat history if I clear cookies?
A: No. Your chat history is stored on OpenAI's servers and tied to your account email, not your browser cookies. You'll see all your previous conversations once you log in successfully.
What to remember
- Login loops are browser cookie problems, not account bans
- Clear OpenAI cookies specifically, not just "recent" cache
- Third-party cookie blocking is the most common cause
- Incognito mode isolates whether extensions are interfering
- Wrong system time breaks authentication tokens silently
