You can delete unauthorized (or possibly compromised) SSH keys to ensure that an attacker no longer has access to your repositories. You can also approve existing SSH keys that are valid.
In the upper-right corner of any page, click your profile photo, then click Settings.
In the user settings sidebar, click SSH and GPG keys.
On the SSH Settings page, take note of the SSH keys associated with your account. For those that you don't recognize, or that are out-of-date, click Delete. If there are valid SSH keys you'd like to keep, click Approve.
Note: If you're auditing your SSH keys due to an unsuccessful Git operation, the unverified key that caused the SSH key audit error will be highlighted in the list of SSH keys.
Open Terminal.
Start the ssh-agent in the background.
$ eval "$(ssh-agent -s)"

If you are using Git Bash, turn on ssh-agent:
# start the ssh-agent in the background
$ eval "$(ssh-agent -s)"
> Agent pid 59566
If you are using another terminal prompt, such as Git for Windows, turn on ssh-agent:
# start the ssh-agent in the background
$ eval $(ssh-agent -s)
