Most of the time Google keeps signing you out because of cookies, security checks, or a misconfigured browser setting rather than a “big bug.”

Why does Google keep signing me out?

Main reasons it happens

Think of your Google login as a ticket your browser holds using cookies. If anything keeps throwing away or invalidating that ticket, you get signed out.

Common causes:

  • Cookies are disabled or set to delete on exit, so your sign‑in can’t be remembered between sessions.
  • Your browser is set to clear data (cookies/cache) automatically when you close it or via a policy (work/school device).
  • Extensions (especially privacy, VPN, or security add‑ons) interfere with cookies or sign‑in sessions.
  • You’re signing in from multiple devices or locations, and Google flags it as suspicious and forces re‑logins for safety.
  • Using Incognito/Private or Guest mode, which never saves sign‑in between windows.
  • Out‑of‑date browser or corrupted cache causing session issues.
  • Account security changes (password reset, 2‑Step Verification, passkeys changes) that invalidate old sessions.
  • Enterprise / managed policies (on work or school computers) that enforce “clear data on exit” or block persistent sign‑in.

Users on forums frequently report that Chrome logs them out every time they close the browser even when settings look correct, and it often traces back to policies or cookie‑clearing options they didn’t realize were enabled.

Quick step‑by‑step fixes

Follow these in order; you can stop as soon as the problem goes away.

  1. Check cookies are allowed
    • In Chrome/Edge/Firefox, go to Settings → Privacy & security → Cookies and site data.
    • Make sure cookies are allowed and that “Block all cookies” or similar isn’t turned on.
 * Turn off any option like “Clear cookies and site data when you close all windows.”
  1. Make sure Google isn’t set to auto‑sign out
    • In your browser’s site settings, ensure accounts.google.com and google.com are not blocked from using cookies.
 * In some setups, you can add Google sites to “Always allow cookies” to keep you signed in.
  1. Turn off aggressive extensions temporarily
    • Disable ad blockers, privacy tools, VPN extensions, or “auto‑clean cookies” add‑ons one by one.
 * Restart the browser and sign in again to test if the issue stops.
  1. Update your browser
    • Go to your browser’s About page and install any pending updates.
 * Outdated browsers can mishandle modern authentication and trigger repeated sign‑outs.
  1. Clear cache (but keep an eye on cookies)
    • Clear cached images and files; if you clear cookies, you’ll need to sign in once more afterward.
 * If the problem started after a big update or crash, a fresh cache often stabilizes sessions.
  1. Check Google Account security
    • Visit your Google Account → Security, and look for alerts about unusual activity or new logins.
 * If you recently changed password, enabled 2‑Step Verification, or added/removed passkeys, some old sessions may be forced to sign in again, which is normal.
  1. Look for work/school policies
    • On managed devices, admins can push rules like “ClearBrowsingDataOnExit,” which log you out every time.
 * If this is a work or school machine and you see those policies, you may need IT to relax them.

A quick example story

Imagine you’ve just installed a privacy extension that auto‑deletes cookies each time you close your browser. At first it seems great, but the next morning Gmail asks you to log in again, your YouTube recommendations reset, and Google Drive wants another sign‑in. You blame Google, but what’s actually happening is that the extension quietly throws away your login “ticket” at shutdown, so Google treats each new session like a fresh, unknown visitor.

If it still keeps happening

If nothing above works:

  • Try a different browser (e.g., Firefox vs Chrome) to see if the issue is browser‑specific.
  • Create a new browser profile and sign in there; profile corruption can break sign‑in persistence.
  • Check for antivirus or cleanup utilities that “optimize” by deleting browser data automatically.

If you share some details like device (Windows/Mac/Android/iOS), browser, and whether it happens only after restarting or all the time, I can narrow this down to a more tailored set of steps for you.
