I've got a Git remote repo installed on a VPS. All the (physical) users of this git use the same user/password, and I would like to change the password.
In order to clone the git repository we use ssh like that :
git clone -v "ssh://email@example.com/my/user/my-project"
There is no password for git, as git doesn't handle authentification.
If you need to change your server user's password, just issue theses commands:
ssh firstname.lastname@example.org passwd
It is recommanded to have a either a very strong password or using a key-based authentification, since this will be subject to bruteforce as every public ssh server.
