I started having issues opening a password protected entry across extensions/desktop/mobile. Went to https://www.reddit.com/r/Bitwarden/ and there are a bunch of posts in the past few days talking about similar issues
How do you guys keep your Bitwarden backed up? This reminded me to properly set that up. For now, I just exported the file and left it encrypted on a separate drive.
I go do a manual export to CSV every few weeks, then store that in a cryptomator vault I use for important stuff.
