It is recommended to use one key per client. It means if you access your Codeberg repository from your home PC, your laptop and your office PC you should generate separate keys for each machine.
In the context of Codeberg you should decide yourself if you add a passphrase to your SSH key or not. Read the on-going discussion about that topic in this [Codeberg-Issue](https://codeberg.org/Codeberg/Documentation/issues/2).

## Add the SSH key to Codeberg
1. Copy the SSH key to your clipboard. Attention: Copy only the public part of the key not the private one. You can identify it by the `.pub` extension. By default, you can find the public key in `$HOME/.ssh/id_rsa.pub`.
