SSH authentication is generally preferred over password-based authentication for several reasons:

Security: Passwords are easily guessed or hacked, whereas SSH authentication relies on cryptographic keys, which are much more difficult to crack.
Convenience: Once you’ve configured SSH authentication, logging in to a remote system becomes much easier. You don’t need to remember or type in a password every time you log in; instead, you just need to have your SSH key handy.
