I guess that's just an SMS in combination with a password instead of an authenticator app.
Next time you log into KLM/AF website or the Flying Blue website, in the log-in window, select "Log in with authenticator app" -- from here, you can setup the authenticator app and start using it instead of the PIN (SMS/Email).
