password saver/manager

[Skaperen]

is there any nice Python3 script around that can save/manage passwords for end user usage (not for servers to authenticate with) that includes additional data such as the sign-up email that might be needed some day for password reset? i need to replace the password keeper i have now. something that can interface with Firefox would be a plus. graphical or text user interface (even commands) is OK.

all stored data must be strongly encrypted, of course.

For years I am using Keepass (on Windows) and it's Linux port (now crossplatform) KeepassX. There are also other ports. I also use the port for android.

Keepass is open source (OSI certified). KeepassX is also open source.
Not python though, but I am very satisfied and recommend it. Reach in features/options/data that can be stored, customization, etc. A lot of plugins for Keepass. Have a detailed look on the site.

ubuntu 18.04 has package 'keepassx' that also installs the dependencies (several needed on plain ubuntu).
