Microsoft edge signed me out of all websites

Hi Mahmoud,

Like Google Chrome and other browsers, cookies can be erased once in a while when Windows or the Browser gets update. It is normal thing.

If it happens repeatedly, your antivirus might be playing a part. May I know one are you using?

I’m eager to hear back and work together to find a solution.

Unexpected sign-outs usually mean either:

• Site cookies/session tokens were cleared or expired, or
• Sync/identity state changed so sites no longer recognize the signed-in session.

Since cookies, passwords, and history are still visible, focus on Edge’s profile, sync, and sign-in state.

1. Confirm the correct Edge profile is active
   • In Edge, check the profile icon in the top-right corner.
   • Make sure the expected profile is selected (the one that previously held your sessions). If Edge created or switched to a new profile, existing cookies/sessions from the old profile will not be used.
   • If an unwanted extra profile was created and is being used by default, switch back to the original profile and optionally delete the extra one so Edge stops using it.
2. Check if sync or sign-in changed
   • Go to Settings and more > Settings > Profiles.
   • Verify the profile is still signed in with the same Microsoft account and that Sync is turned on if you use it.
   • If you recently signed out or removed the profile, sites will treat this as a new browser and require sign-in again. Sign back in to the profile and re-enable sync if needed.
3. Verify cookies and site data settings
   • Go to Settings and more > Settings > Privacy, search, and services.
   • Under Clear browsing data, make sure you haven’t configured Choose what to clear every time you close the browser to clear Cookies and other site data. If that is enabled, Edge will sign out of sites whenever all windows are closed.
   • Also ensure you didn’t manually run Clear browsing data with Cookies and other site data selected.
4. Re-sign into affected sites and let Edge resave credentials
   • Visit the sites that signed out and log in again.
   • Edge will offer to save or autofill passwords if Offer to save passwords is enabled under Settings and more > Settings > Profiles > Passwords.
   • Once re-signed in, sessions should persist as long as cookies are not cleared and the site itself doesn’t force frequent re-authentication.
5. If the problem repeats, check for external factors
   • Confirm no other software (security tools, “cleanup” utilities, or group policies) is clearing Edge’s cookies or profile data.
   • If using work/school accounts, admins may enforce sign-out or session lifetime policies that override local browser settings.

If cookies and profile are intact but you were signed out once, it is typically a one-time session reset (for example, after an update or policy change). After re-signing into sites and confirming that Edge is not set to clear cookies on close, sign-ins should persist.
