My dad insisted on using CARDFILE.EXE from Windows 3.1 up until he switched to a MacBook in 2010 or so. I still have the data file somewhere.
Gotta admit tho, it was one of the most useful applications that came with a PC back in the late 80s/early 90s. My folks put everything into that thing. They probably had about 350 cards!
Perhaps a bit more technically involved for some tastes, but here’s my setup –
I’ve used pass for the past few years, a command line based password manager that stores GPG encrypted passwords as text files in a git repository. I use it for more than passwords, so it’s more like a passwords-and-other-sensitive-secrets manager.
There’s no defined structure, that is left to the user to figure out, but the basic command to get a password and copy it to the clipboard simply grabs the first line of the file, which is where I insert the actual password. There’s other info in there too, usernames, challenge questions, etc.
I push the git repo to gitlab, transported via ssh. On my phone, I use a client for Android called Android Password Store, which pulls from the git repository and has an easy interface for adding, editing, and accessing the passwords.
It costs nothing, stays backed up, and works pretty well for my purposes. Despite that, I was looking around to see if KeePass would be a better solution for me in any way, and found this cool thing, passhole, which provides KeePass with a CLI interface similar to that of pass, which is a big part of my attraction to it.
Well, here’s a thing I didn’t know about before that might be useful to you – a tool to extract the dated from the *.crd files.
