I have a website which commits to a git local repository all the changes done.
I need to automatically push them directly from the web server to a remote Bitbucket repository.
The authentication method I use to do it is by passwordless SSH key stored on the Web Server, but I think this could be not so secure.
So the question is... do you know a more secure (or simply better) method to automatically push changes from a Web Server to a Git-Bitbucket private repository?
