# How to copy SSH keys to another machine?

Public key authentication is generally safer than password-based and is way more convenient.

SSH offers a command to set it up, `ssh-copy-id` (part of the openssh client package) will copy your public key to the remote machine.
Use it like this:

```bash
ssh-copy-id -i ~/.ssh/my_key.pub remote-machine
```

You’ll be prompted your password, and your public key will be appended to the remote machine’s `~/.ssh/authorized_keys` file.

Note: Remember to use `ssh-keygen` to first generate a pair of keys if you don't have any.
