Back to DocsWhy store them here
SSH keys saved on your account act as an address book. Instead of pasting a public key every time you build a server, you keep your keys in one place and pick them when they are needed.
Adding a key
Add the public key — the contents of a file ending in .pub, one line starting with something like ssh-ed25519 or ssh-rsa.
Never paste a private key anywhere, here or otherwise. If you do not have a key pair yet:
- `ssh-keygen -t ed25519 -C "you@example.com"`
- The public key is then in `~/.ssh/id_ed25519.pub`
Using them on a server
When you create or reinstall a server, choose which stored keys to install. They are placed in the root user's authorised keys so you can log in immediately, without waiting for a password.
Adding or removing later
Changing keys on your account affects servers built afterwards, not ones already running. To change the keys on an existing server, edit ~/.ssh/authorized_keys on the machine itself, or reinstall it with the new selection.
