@Rlb1 think this is related to Aggregate Topic: Lost Passwords in July 2024 update
I’m out and about so just going to tag in @Mattches as situation varies a bit, at least so he’s aware but I’m assuming just reference ongoing issue.
Beyond that, can you advise which method you used to install Brave, which specific OS you have (such as with Linux is it Mint, Debian, etc), and possibly test to see if the same thing happens on Beta or Nightly versions of Brave?
