Other features include auto-type, Twofish encryption, YubiKey challenge-response, TOTP generation, CSV import, command-line interface, DEP and ASLR hardening, stand-alone password and passphrase generator, password strength meter, and more.
You then need to set a master password, something you won't forget or maybe have written down. They are easy to set up, but you can get lost in the options including expire date, icons, properties, and more. Multiple databases are supported as well as multiple groupings within each database. On the first startup, you will need to create a database named whatever you like. KeePassXC is a community fork of KeePassX with the goal to extend and improve it with new features and bugfixes. KeePassXC can store your passwords safely and auto-type them into your everyday websites and applications.
You shouldn't waste your time trying to remember and type your passwords. The thing computers can do best is storing information.
