Introducing pass
Password management should be simple and follow Unix philosophy. With pass, each password lives inside of a gpg encrypted file whose filename is the title of the website or resource that requires the password. These encrypted files may be organized into meaningful folder hierarchies, copied from computer to computer, and, in general, manipulated using standard command line file management utilities.
pass makes managing these individual password files extremely easy. All passwords live in~/.password-store and pass provides some nice commands for adding, editing, generating, and retrieving passwords. It is a very short and simple shell script. It’s capable of temporarily putting passwords on your clipboard and tracking password changes using git.
You can edit the password store using ordinary unix shell commands alongside the pass command. There are no funky file formats or new paradigms to learn. There is bash completion so that you can simply hit tab to fill in names.
The pass command is extensively documented in its man page.
