# 4. Enrolling the public key to Key9

\*\* NOTE: If your Yubikey is already enrolled with Key9, you can skip these steps!

You need to obtain the public key, which will be the SSH public key that you copy/paste to Key9. To get the public key, run:

`$ ssh-keygen -D /opt/homebrew/lib/libykcs11.dylib -e`

This will return two public keys. *Copy and paste the <mark style="color:yellow;">first public key</mark> into the Key9* "PUBLIC KEY" field in the SSH section of your account.&#x20;

Login into Key9 and in the top right corner will be your name with a “pull down” menu option.  Pull that down and go to “My Profile”.  Once in your profile,  select “Add SSH Key” (right of “SSH Keys”).&#x20;

Give your new key a name and copy/paste the public key.
