KeePassXC has a plethora of features that make it much more useful than a text file.
In a kdbx database, I can store the password to my bitcoin wallet. I can store the seed. I can store the master public key, I can store the master private keys. (extended too). I can store a CVS file of all public keys for all addresses. Also a CVS file of payment addresses.
I can store URLs (encrypted), notes, and all kinds of other things. It has a password generator for secure random passwords.
It has YubiKey support. And KeyFile support.
I could not live without KeePassXC.
The only thing that I don’t like is that every time you save a new password, or change the database in any way, the entire database needs to be re-uploaded to the cloud.
So if I have a database that has a lot of large files attached, every time I edit anything in the database, the whole 400mb database has to be re-uploaded to my cloud storage provider. But this is a minor gripe.
