Description After updating Brave to version 1.91.171 (Chromium 149.0.7827.103), I launched the browser and it displayed that the update had completed successfully. Immediately afterward, I found that I had been signed out of nearly every website I was logged into, including Google and many unrelate…

I can look into this but this does not appear to be a widespread issue. Just to confirm, you didn’t actually lose any of your data, you were just logged out of your sessions/accounts, correct?

yes data is ok, only some of my accounts this happen every time i update some accounts like telegram stay but most of cdn based or google stuff log out

Do you have any software installed on your PC that runs automatically that clears space – like cCleaner or something simlar? Additionally, did this happen across all three of your profiles or just one of them?

Similar thing happened to me, but also i got my passwords deleted from password manager.

yes all three profiles and no app

Yeah, i saw different post talking about their passwords being deleted, this bug has been there for a while. Check them out, maybe it will help you with your problem.

Facing the same issue after update

Mass logout from nearly all websites immediately after updating to Brave 1.91.171 (Windows 11)
