How to authorize by key for a third-party project with github?

Question

GitHub

Hello.
There is a key. The public part of the key has been added to the github account.
I clone the project from github. Requests username/password.
I make a commit, send it to the server. Again it asks for the username and password from the account.
How to log in by key so as not to constantly enter the login and password from the account?
