Hello,

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

    Under .ssh, i have only one file called Authorized_keys.

    It does ask me for a password but when i enter it, it gives me an error:
    Failed to load key /root/.ssh/authorized_keys: incorrect passphrase supplied to decrypt private key

      I believe this is because the “rsaid” he’s referring to is the name of the ssh key (not the authorized keys file). As I recall, the tutorials refer to the rsaid file as the key itself (e.g. https://www.digitalocean.com/community/tutorials/how-to-set-up-ssh-keys-on-debian-10).

      For example, if you named the key “MySSHKey”, you would run the command against that file (ssh-keygen -p -f /locationOfKey/MySSHKey). By default, if you name the SSH key, it goes into your home folder (~).

      Also, when you talk about the authorized_keys file, that should be on the server side. The SSH key should be on your client computer that you’re remoting in from.

      Hope this helps!
