Description
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.
Syntax
The first line is always the password.
If you want to add more information then the syntax is similar to a key:value pair.
So if you want to add a password with a username and the url of the website then it would look like this:
Very secure password
username: example_username
url: https://example.com
It is a good advise to keep a syntax for your values so the parsing of other pass tools and scripts are able to parse your files. I suggest to use username and and url to keep consistency.
