If your browser keeps signing you out, the sign-in data is usually not surviving: the browser or an extension deletes site data when all windows close, a Cookie rule breaks the login flow, or the website ends the session by policy. First identify what is losing state: one website session, every website, the browser's own sync account, or an organization profile. Clear only the affected site's data after you have recovery methods available, and treat unexpected account activity as a security event rather than a browser setting problem.

Key Takeaways

A website session, browser sync account, and browser profile are different identity layers.

Being signed out after closing every window often points to site-data retention or intentional session policy.

Third-party Cookie controls can affect sign-in flows that move between related domains.

Clearing Cookies signs you out; start with one site, not the whole browser.

Do not weaken privacy controls on shared or managed devices just to keep a session open.

Use the device and app troubleshooting guide when the problem also affects other apps, accounts, or networks.

Which account is losing its session when the browser keeps signing you out?

Name the identity layer before changing settings. A browser can display several independent sign-in states at once:

Sign-in layer	What it controls	Useful observation
Website session	Access to one service or group of related sites	Only that site returns to its login page
Browser sync account	Bookmarks, tabs, history, passwords, or browser settings	The browser toolbar says sync is paused or signed out
Operating-system account	Device sign-in, keychain, work profile, or managed credentials	Other apps or system prompts also ask again
Organization single sign-on	Access through an identity provider and policy	Login redirects to a work or school domain

Write down the exact site, account type, time, and trigger. Does the session disappear after closing one tab, quitting the browser, restarting the computer, changing networks, or waiting a fixed period? Does it affect one account or every account in that profile?

Do not test by signing into a stranger's account or sharing your password. If you need an account comparison, use another account you own and are authorized to access. On a shared computer, a session ending when the browser closes may be an intended privacy control.

If the browser's own sync account is signing out while website sessions remain active, use the browser vendor's sync or profile support path. Deleting website Cookies will not repair a revoked sync token and may create additional sign-ins.

Why does the browser keep signing you out after it closes?

Websites commonly store a session identifier or related state in Cookies or other on-device site data. If the browser deletes that state when all windows close, the next visit starts without the previous session.

Chrome documents three on-device site-data behaviors: allow sites to save data, delete saved data when all windows close, or prevent sites from saving it. It notes that deleting data on close makes sites less likely to remember you across visits.［1］ Check the browser's actual setting and any site-specific exception instead of assuming that all data is persistent.

Also check how you close the browser. Some systems keep a browser process running after its last window closes; others end it. Test with a complete quit and a normal reopen, then compare a computer restart. If the sign-out happens only after a long idle period, the website may enforce a server-side session timeout rather than the browser deleting anything.

Do not use a private or guest window to test persistence. Those modes are designed to isolate or discard ordinary session state. A private-window sign-out after closing the window is expected and does not prove a defect.

If a cleanup utility, privacy extension, parental-control tool, or enterprise policy clears data on exit, identify the owner before changing it. On a managed device, the setting may return after every restart because policy is reapplying it.

Why does Chrome keep signing you out of your Google Account?

A Google site such as Gmail and the Chrome profile are separate sign-in layers. Gmail can ask for your password while the toolbar still shows your profile, or sync can pause while Gmail stays open. Note which one asked you to sign in again before changing settings.

If the Google sign-in disappears every time Chrome closes, check the on-device site-data setting described in the previous section: if Chrome deletes site data when all windows close, Google cannot keep that session. The same limit applies to any “Keep me signed in” or “Stay signed in” box: it works only while that site's data survives a restart.

If Google signs you out on several devices at once or sends a security alert you did not trigger, stop adjusting Chrome and review the account from a trusted device, as described in the section on expected and unexpected sign-ins below.

Cookies keep signing me out: can Cookie rules break a website login?

Yes. A first-party Cookie usually belongs to the site shown in the address bar, while a login can also involve an identity provider, embedded content, payment provider, or related domain. Blocking third-party Cookies can interrupt some of these cross-site flows even when the main site's own Cookies are allowed.

Chrome warns that sites may not work as expected when they cannot save Cookies, and that sites relying on third-party Cookies can fail unless a specific exception is allowed. It also describes related sites using shared activity to keep a user signed in across a group.［2］ This does not justify allowing third-party Cookies everywhere.

Use a narrow test:

Confirm the legitimate domains involved in the login redirect.
Check the affected site's Cookie and site-data status.
If the browser shows a blocked-Cookie indicator, review that site's documented requirement.
Allow only the necessary trusted site temporarily, if your privacy policy permits it.
Sign in again and repeat the original action.
Remove the exception if it did not change the result.

Do not add a broad wildcard copied from an unknown forum. A look-alike domain can capture credentials, and an unnecessary exception expands tracking. If a service cannot explain why a third-party domain is required, ask its support team before allowing it.

The cache and cookies guide explains why cached page files and login state are not interchangeable. Clearing cache alone may refresh a page without ending a session; clearing Cookies normally changes authentication state.

How should you clear site data without losing everything?

Before clearing anything, make sure you can sign in again. Confirm your password manager or passkey works, your recovery email or phone is current, and any hardware key or authenticator is available. Save drafts, carts, form work, and offline data that the site stores locally.

Then remove only the affected site's history, Cookies, and data through the browser's site-data controls. Mozilla's login guidance recommends checking that Cookies are enabled, clearing history for the affected site, checking add-ons and security applications, and only then considering a broader Cookie cleanup. It warns that removing the profile Cookie database signs the user out of all saved website sessions.［3］

After the targeted clear:

Close all tabs for that site.
Open one new tab and navigate through the site's official home page.
Sign in once; do not submit the form repeatedly.
Complete any required verification.
Close and reopen the browser normally.
Record whether the session survives and for how long.

If the targeted clear does not help, do not immediately clear every site. Compare a fresh browser profile first. A fresh profile preserves the original profile as evidence and tells you whether the issue follows the website account or stays with local browser state.

Apple notes that removing Safari website data can sign users out, change website behavior, and affect data used by other apps.［4］ That is another reason to use the smallest possible scope and understand the device ecosystem before deleting broadly.

Could extensions, password tools, or managed policy cause sign-outs?

Extensions that block trackers, rewrite requests, clear Cookies, isolate sites, manage containers, automate form filling, or change proxy settings can disrupt authentication. A password manager may fill credentials correctly while the session Cookie still fails; successful form filling does not prove the login state was retained.

Test extensions one at a time in the affected profile. Record the enabled list, disable the most relevant extension, restart the browser, and repeat the same sign-in and close/reopen sequence. If the symptom disappears, update the extension and review its permissions before re-enabling it. Use the extension safety checklist for unfamiliar ownership or permission changes.

Do not disable organization extensions, endpoint protection, or an identity-provider helper without approval. A managed policy can require reauthentication, delete site data, block password saving, or prevent persistent sessions. Ask the administrator whether the behavior is intentional and provide the exact browser profile, website, redirect domain, and time.

Also distinguish an extension problem from a browser compatibility problem. If the same account stays signed in with a fresh profile but not the original profile, local state is more likely. If the account is signed out across browsers and devices, the website or account security state is more likely.

Website keeps logging me out: when is repeated sign-in expected?

Some sessions are designed to expire. Banking, health, administration, enterprise, and other sensitive services may end sessions after inactivity, device changes, password changes, risk signals, or administrator action. A site can also revoke every session after account recovery or a security event.

Expected reauthentication usually has a consistent trigger and an official explanation. Unexpected behavior deserves more care when it includes:

Sign-out across several browsers or devices at the same time.
Password-reset or new-login notifications you did not initiate.
Unknown devices, sessions, recovery methods, or forwarding rules.
A site redirecting to a domain you do not recognize.
Repeated multi-factor prompts without your own login attempt.

If those appear, stop changing browser settings. Use a trusted device and the service's official account-security page, change the password if appropriate, review active sessions, protect recovery methods, and contact the provider. The unexpected account login guide covers that response. The session hijacking explainer explains why an active session must be protected separately from the password.

Do not try to preserve a session on a public, borrowed, or shared computer. Sign out intentionally, avoid saving credentials, and remove any account you added to the browser profile. Convenience is not the correct goal on a device you do not control.

What evidence should you give support or IT?

Prepare a short timeline instead of sending a full browser profile or Cookie database:

Website and legitimate login domains, without private query tokens.
Whether the website session, browser sync, or operating-system account is affected.
Browser, version, operating system, profile type, and whether it is managed.
Trigger: closing a tab, quitting all windows, restarting, idle timeout, or network change.
Results in the original profile, a fresh profile, and another current browser.
Whether only one site or every site loses its session.
Exact error text and security notifications.

Never send passwords, one-time codes, passkeys, raw Cookies, session tokens, or a full exported profile. If support asks for those, stop and verify the request through an official channel.

Summary

When a browser repeatedly signs you out, first separate a website session from browser sync, operating-system identity, and organization single sign-on. Check the trigger, site-data retention, Cookie requirements, extensions, and managed policy in that order. Clear only the affected site's data after confirming recovery access. Treat predictable timeouts as policy, but move unexpected cross-device sign-outs or security alerts into the account-security process. Do not weaken global privacy controls or keep sensitive sessions open on shared devices.

FAQ

Why am I signed out every time I close the browser?

The browser, an extension, or a policy may delete site data when all windows close. Private mode also discards ordinary session state by design. Check the profile's on-exit behavior and site-specific exception.

Do blocked Cookies cause repeated sign-outs?

They can. A site may need its own Cookie or a trusted cross-site login flow. Use a specific exception only when the legitimate service documents the requirement; do not allow third-party Cookies globally.

Will clearing cache keep me signed in?

Cache and Cookies serve different purposes. Clearing cached page resources may preserve a login, while clearing Cookies or site data usually ends the session.

Should I clear every Cookie in the browser?

Start with the affected site. A global clear signs you out broadly and can remove preferences or local work without proving the cause.

Why does login work in another browser?

The browsers may have different Cookie rules, extensions, profiles, proxy paths, or managed settings. Repeat the test with the same account, network, and time before drawing a conclusion.

Is a forced sign-in always an account-security problem?

No. It may be a normal timeout or site-data rule. Unexpected sign-outs across devices, unknown login notices, or unrequested security prompts are stronger reasons to review the account.

Should a shared computer remember my login?

No. Use a private session if permitted, do not save credentials, and sign out when finished. Persistent access on a device you do not control creates unnecessary risk.

What should I send to support when the browser keeps signing me out?

Send the affected identity layer, browser and system versions, trigger, exact error, and comparison results. Never send passwords, verification codes, Cookies, tokens, or full profile archives.
