SE Secure Password Generator
you want to have lengthy, complicated and unique passwords for every website that you use but that rarely happens in practice because complex passwords are impossible for anyone to remember.
Some people rely on password managers like LastPass or KeePass – they store all your passwords in an encrypted database which is then protected by a master password. You enter the master password and you instantly have access to all your stored user logins and passwords. LastPass and 1Password also offers apps for mobile devices.
