KeePassXC might be worth looking at for you. Open Source and a version on every platform including both mobile OS's. I then use something to sync the files across all my devices. But you could do that with a cron job too.
I have to use a PW manager. I bet I have over a thousand passwords and they all look something like this:
So no way I'm remembering that. I remember a single password to open the encrypted file that holds all the passwords.
The girl knows the password so if I die she has access to everything. Every two weeks the file is put on a thumb drive with everything else I want backed up, taxes, personal documents, etc and put in my safe deposit box. 2FA is used when available. I also have copies of the master file on each device since I sync those.
