| Checking for existing SSH keys | Before you generate an SSH key, you can check to see if you have any existing SSH keys. |

Check for existing SSH key |
{% data reusables.ssh.key-type-support %}
{% data reusables.command_line.open_the_multi_os_terminal %}
2. Enter ls -al ~/.ssh to see if existing SSH keys are present.
$ ls -al ~/.ssh
# Lists the files in your .ssh directory, if they exist
- Check the directory listing to see if you already have a public SSH key. By default, the {% ifversion ghae %}filename of a supported public key for {% data variables.product.product_name %} is id_rsa.pub.{% elsif fpt or ghes %}filenames of supported public keys for {% data variables.product.product_name %} are one of the following.
- id_rsa.pub
- id_ecdsa.pub
- id_ed25519.pub{% endif %}
{% tip %}
Tip: If you receive an error that ~/.ssh doesn't exist, you do not have an existing SSH key pair in the default location. You can create a new SSH key pair in the next step.
{% endtip %}
- Either generate a new SSH key or upload an existing key.
-
If you don't have a supported public and private key pair, or don't wish to use any that are available, generate a new SSH key.
-
If you see an existing public and private key pair listed (for example, id_rsa.pub and id_rsa) that you would like to use to connect to {% data variables.product.product_name %}, you can add the key to the ssh-agent.
For more information about generation of a new SSH key or addition of an existing key to the ssh-agent, see "Generating a new SSH key and adding it to the ssh-agent."
