These tests I’ve used in the past give a very good overall idea of any platform you are testing: I’ve recently had the pleasure of testing a few large scale storage systems and my co-worker and I needed to come up with a number of tests to determine their overall performance when it comes to Macs. …then supply your old and new passphrase (twice) at the prompts. To change the passphrase of an existing keypair: In order to properly use the keypair, you will need to distribute the id_rsa.pub file to each server you intend to authenticate to. Once generated, both files (id_rsa and id_rsa.pub) will exist in your ~/.ssh directory. The caveat is that you will need to type in the passphrase each time you use the key.

Should your private key fall into someone else’s hands, they will potentially have access to all services that use said key, UNLESS you have password protected said key. The security of a key, no matter how encrypted, is still dependent on the fact that it is not visible to anyone else. It is a good idea to pick a password to use instead of leaving empty. Press Enter here, as its default (~/.ssh/id_rsa) is sufficient. Once executed, you will be prompted with a number of questions: In macOS, by default, SSH keys are stored per user in their hidden folder ~/.ssh.
Only that unique keypair will be able to work together.
Therefore, when you do authenticate, your private key (that is never given out, EVER), is used to encrypt/decrypt data that only the public key can subsequently encrypt/decrypt. Prior to being able to authenticate, you need to give the public key to what you are intending to authenticate to. Those two files are mathematically/cryptographically tied together in a way where a separate key would not be able to unlock it, hence the term ‘keypair’. When a key is generated, two files are created, a private key, and a public key. Keys add a level of security that standard username/passwords don’t provide. For security, a number of services may use SSH keys for authentication rather than a standard username/password.
