Password Authenticator

Password Authenticator provides an easy interface to setup standard username-password authentication with 3rd party services.

Simply calling authenticate() should load the related account with required credentials.

Inheriting class should implement:

  • get_token() that tests username-password combination or gets a new session token to be used for future calls
