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.
It's definetly a good idea to export a backup just in case. I have a local desktop backup with KeePassXC and every couple of months or so I export the file, encrypt it and upload a copy on proton drive and another on a personal external drive
