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 always prinf offline. In fact my printer was connected to network once, when setting up.
