Just recently, I was steered to this site..
https://www.passwordstore.org/
And in there, I realized that a very simple self-managed password "vault" can be created with just using gpg from the command line.
For example, if you wanted to store a password for Ebay..
gpp -o pw-for-ebay.gpg -e -r [myID] -
..and the system will open stdin for typing. when done, hit new-line, and ctrl-C [probably ^D in linux], and the file is created with the string stored inside.
H:\temp>gpg -o pw-for-ebay.gpg -e -r august -
File 'pw-for-ebay.gpg' exists. Overwrite? (y/N) y
updated pw is ... blahblahblah111
^C
When you need to view the pw:
H:\temp>gpg -d pw-for-ebay.gpg
gpg: encrypted with 2048-bit RSA key, ID 583B29AD69D0999F, created 2020-01-02
"August Abolins <
august@kolico.ca>"
updated pw is ... blahblahblah111
So.. it's relatively simple to have a safe directory with all the pw*.gpg files like that.
Combine that with rclone and a remote defined as "crypt", you can keep a copy of the directory in the cloud where you could access the contents from any other device that has rclone.
