Do I have to use the two-factor authentication if I am a music user?

Logging in with the two-factor authentication is optional for music users. You can set it up and deactivate it at any time. You can find the setting up options on the Online Portal under My details. 

We recommend that you use the two-factor authentication in any case in order to protect yourself from identity theft and a leakage of sensitive data. In addition, your customer account is then optimally secured.
