@inachara It does depend on your threat model but paper isn't that safe either, unless you are using some kind of cipher. However, that would get really tedious. For most people, I would recommend keeping sensitive data in an external encrypted hard drive. You can use something like @cryptomator or #KeePassXC.
@sudo
Are YOU joking? Why put sensitive information on anything besides paper?
