If Gmail repeatedly asks you to sign in, note when it happens: after closing the browser, after a device restart, during ordinary use, or only on a managed computer. The timing helps distinguish a disappearing session from a security or policy requirement.
Check whether the browser is meant to retain sessions
Guest and private sessions are temporary. If you want persistent access on your own trusted computer, use an ordinary browser profile and keep the device protected.
Review browser settings or cleanup software that deletes cookies or site data when the browser closes. Google needs cookies for account sessions. A browser can allow them during use but remove them at exit, producing a new login request every time.
Inspect the affected profile
- Confirm that you reopened the same browser profile.
- Update the browser through its normal update mechanism.
- Check site-data exceptions affecting Google.
- Review recently added extensions or cleanup settings that could interfere with the session.
- Change one relevant setting at a time, then retest.
Saving a password is not the same as keeping a session signed in. A password manager may make reauthentication easier, but does not prevent Google or an organization from requiring it.
Separate expected sign-outs from faults
Signing out of all Google accounts in another tab of the same browser context affects the shared sessions. On work or school systems, administrators can impose session and sign-in requirements. Ask about those policies instead of attempting to defeat them.
A verification challenge for a sensitive action can also occur while you remain signed in. Record the exact message rather than treating every password or identity prompt as the same symptom.
Use cleanup sparingly
Google lists clearing browser data as a troubleshooting option, but it deliberately ends sessions and can remove useful local information. First save work and confirm recovery access. If cleanup is necessary, prefer the narrow relevant site-data scope supported by your browser rather than deleting everything.
If you also see unfamiliar account activity, review security from a trusted device. Do not disable 2-Step Verification merely to reduce prompts; that weakens protection without identifying why sessions are ending.
