Using Local Password Authentication

You can explicitly configure the password authentication method or use this method as a fallback mechanism when remote authentication servers fail. The password authentication method consults the local user profiles configured at the [edit system login] hierarchy level. Users can log in to a router using their local user name and password in the following scenarios:

• The password authentication method (password) is explicitly configured as one of the authentication methods in the [authentication-order authentication-methods] statement. In this case, the password authentication is consulted if no previous authentication accepts the logon credentials. This is true whether the previous authentication method fails to respond or returns a reject response due to an incorrect username or password.
• The password authentication method is not explicitly configured as one of the authentication methods in the [authentication-order authentication-methods] statement. In this case, the password authentication method is consulted only if all configured authentication methods fail to respond. It is not consulted if any configured authentication method returns a reject response due to an incorrect username or password.
