You and someone else have mentioned the deadman switch, does the other person need an account or can credentials be made for them? I haven’t used bitwarden in a while (since I migrated to gopass and then to keepass), so I’m guessing this is a new feature.
That is a very fascinating feature and I think I’ll look into it!
Whatever file format I use them in is also how I back them up, I backup my entire desktop’s and laptop’s data to an external hard drive and an online service provider. I’m sure a compressed format would be more space efficient but that would take much more time given my use case.
In the case of my laptop it runs Linux and the filesystem I use supports “transparent compression” (almost all contents of the drive are compressed with zstd), so I’m guessing any of the ROMs on there will have already been compressed as nuch as they can (but I’m not knowledgeable enough on the file format specs)
