How do I delete my SSH key?

Depending whether you're looking to remove an SSH key from your account, or just from your Linode, there are 2 different ways to go about this:

To delete an SSH key from your account:

• Head over to the "SSH Keys" tab of the "My Profile" section of the Cloud Manager.
• Click the 3 dots to the right of your SSH key and then click "Delete".

To delete an SSH key from your Linode:

• Login to your Linode via SSH or Lish.
• Open the file ~/.ssh/authorized_keys with your favorite editor. Examples for nano and vim can be found below:

# With nano:
nano ~/.ssh/authorized_keys

# With vim:
vim ~/.ssh/authorized_keys

Whichever editor you choose, simply delete the key from the file and save.

@OP --

If you've ever logged on to Linode from your Linode, e.g.,

my_linode: $ ssh my_linode

you'll have to delete the appropriate entry from ~/.ssh/known_hosts as well…otherwise, you'll get a nasty error from ssh(1).
