SSH introduced general public critical authentication like a more secure option on the older .rhosts authentication. It enhanced security by avoiding the necessity to have password saved in documents, and eliminated the potential of a compromised server stealing the consumer's password.

A passphrase can be an optional addition. In the event you enter one particular, you will have to provide it when you utilize this vital (Except you happen to be running SSH agent application that stores the decrypted crucial).
