# 3. Enrolling your public key to Key9

The SSH public key needed for Key9 enrollment will be stored in your home directory under a directory named `.ssh` 

You'll want to copy the contents of "id\_ed25519\_sk.pub".   For example,  on a MacOS/Linux system, you can do the following:

`cat $HOME/.ssh/id_ed25519_sk.pub`

Copy and paste the contents of the `id_ed25519_sk.pub` 

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”). 

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