SSH Authenticate with a Password

See more SSH Examples

Demonstrates the Chilkat Ssh.AuthenticatePw method, which authenticates a connected SSH session with a login name and password. The first argument is the login and the second is the password. Call Connect first.

Background: Password authentication is the simplest SSH method, but the password is a secret and should never be a hard-coded literal — obtain it from an interactive prompt, an environment variable, or a secrets vault. On failure, inspect AuthFailReason to distinguish a bad password from a not-connected or already-authenticated state. Public-key authentication is generally preferred for automated jobs.
