How to Change the Passphrase for a Secure Shell Private Key

The following command changes the authentication mechanism for the private key, the passphrase, and not the actual private key. For more information, see the ssh-keygen (1) man page.

  • Change your passphrase.

    Type the ssh-keygen command with the –p option, and answer the prompts.

    mySystem$ ssh-keygen -p
    Enter file which contains the private key (/home/username/.ssh/id_rsa):<Press Return>
    Enter passphrase (empty for no passphrase): passphrase
    Enter same passphrase again: passphrase

    where –p requests changing the passphrase of a private key file.
