The Key That Opens Every Door

For developers, an SSH key is like a master key. Pushing code to GitHub, deploying to a server, running tests in a CI/CD pipeline: SSH key authentication is often what runs behind the scenes.

Once you generate a key with ssh-keygen, you can register the same public key on dozens of services. No passwords to remember, no passwords sent over the wire. One key pair, unlimited doors.

A key you create once is one you'll use for years to come.
