ChatGPT errors, explained
Can't sign in to ChatGPT? Sign-in errors usually come from stale cookies or cache, a browser extension, a wrong or forgotten password, an unverified email, or an OpenAI-side authentication incident. This guide explains the likely causes, the fixes that clear them, and the one security rule that matters: only ever enter your password on the official chatgpt.com.
What's causing it
Sign-in failures have a handful of common causes. Use this to narrow down which one before trying fixes.
| Likely cause | Whose side | What to do |
|---|---|---|
| Stale cookies / cache | You | Clear ChatGPT cookies and cache, or try incognito, then sign in again. |
| Browser extension | You | Test in incognito; if login works, disable extensions one by one. |
| Wrong / forgotten password | You | Reset your password on the official chatgpt.com login. |
| Unverified email | You | Check spam for the verification email; confirm the address is correct. |
| OpenAI auth incident | OpenAI | Check status.openai.com; if there's an incident, wait and switch models meanwhile. |
Don't just sit there
If sign-in is broken on OpenAI's side, or you can't fix it quickly, you don't have to stop. A multi-model workspace lets you switch to another AI and finish what you were doing — then go back to ChatGPT once you can sign in again.
When you can't log in to ChatGPT, switch to Claude, Gemini or another model in the same place and keep going for free — no waiting for OpenAI to recover. Compare answers across models too.

FAQ
Short answers on why sign-in fails, how to fix it, and how to stay safe while you do.
Sign-in problems are usually caused by stale cookies or cache, a browser extension interfering, a forgotten or wrong password, an unverified email, or an OpenAI-side authentication incident. Check status.openai.com first; if it's green, work through clearing cookies, trying incognito and resetting your password.
Clear your cookies and cache, try an incognito window, disable browser extensions, reset your password if needed, confirm your email is verified, and check status.openai.com for an authentication incident. On mobile, update or reinstall the app and sign in again.
Being logged out repeatedly is often a cookie or cache problem, a browser blocking cookies, or an extension clearing session data. Allow cookies for ChatGPT, clear the cache, try incognito to test, and disable privacy extensions one by one. It can also coincide with an OpenAI-side auth incident.
Frequently, yes. Stale or corrupted cookies are a common cause of sign-in failures. Clearing ChatGPT's cookies and cache, or simply using an incognito window, often lets you sign in again. You'll need to enter your credentials afterwards.
Check your spam or junk folder, make sure you entered the right email, and wait a little before requesting another. If your email isn't verified you may not be able to sign in. If it still doesn't arrive after trying, contact OpenAI support.
Yes. Privacy tools, ad blockers and some ChatGPT add-ons can interfere with the sign-in flow or clear session cookies. Test in an incognito window where extensions are usually disabled; if login works there, disable extensions one by one to find the culprit.
On the app, update it to the latest version, check your connection, and sign out then back in. If that fails, reinstall the app and sign in again. You can also try the web app at chatgpt.com to check whether it's an app issue or your account.
It can be. OpenAI occasionally has authentication incidents that stop sign-ins. Check status.openai.com: if there's an auth-related incident, it's their side and you should wait. If it's green, the fix is usually local — cookies, cache, extensions or your password.
The official login is at chatgpt.com. For your security, only ever enter your ChatGPT password on the official site — never on a third-party page, a link from an email, or any site claiming to log you in for ChatGPT. If a page asks for your password and it isn't the official chatgpt.com, don't enter it.
If login is broken on OpenAI's side, or you can't fix it quickly, use a multi-model workspace like MultipleChat to keep working with Claude, Gemini or another model for free until you can sign back in to ChatGPT.
