User Authentication
Different methods can be used to authenticate users in SSH Secure Shell. These
authentication methods can be combined or used separately, depending on the
level of functionality and security you want.
User authentication methods used by the client by default are,
in the following order: public-key, keyboard-interactive, and
password authentication (if available). Public-key and
certificate authentication are combined into the public-key
authentication method. The server allows public-key and
password authentication by default.
Different authentication methods are discussed in more detail in the following sections.
