To change the passphrase for your SSH key, you could use the following command:

ssh-keygen -p -f ~/.ssh/id_rsa

You will be asked to enter the old passphrase first followed by your new passphrase. The output would look something like this:

Enter old passphrase: ****
Enter new passphrase (empty for no passphrase): ****
Enter same passphrase again:                    ****
Your identification has been saved with the new passphrase.

Hope that this helps! Regards, Bobby
