You have the option to whether assign a passphrase or not when creating your SSH private and pubic key pair. How to generate SSH key pair using ssh-keygen This can be changed after the fact as you can perform the following operations on your existing SSH private key using ssh-keygen. Oct 06, 2019 As an example, let’s generate SSH key without a passphrase: # ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/idrsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/idrsa. The passphrase is not just a key to unlock private SSH key, but a part of encryption mechanism. One part is your SSH key, other - the passphrase entered manually. Only if both parts are correct the composite key generated from them on the fly will be valid.
