How do I remove SSH key passphrases from being remembered by Mac OS?

Question

Mac OS X (Snow Leopard).

I accidentally selected the "remember password in my keychain" option when providing the ssh private key passphrase when connecting to a remote server.

Now, when I ssh to the server (even after reboots) it never prompts for the passphrase. How do I get it to prompt me again?

-M

Answer 1

Open up Keychain Access (in /Applications/Utilities/), locate the SSH key (try typing SSH into the search box), right click and choose "Delete".

Answer 2

If you're familiar with the command line: rm ~/.ssh/known_hosts (Note, this will remove all hosts in the 'remembered' list.)
