OTP on first time login

Hello,

This is the first time I’m trying to log in with the default values from documentation here: Setting up the server (New!) | MobileCoach .
However, I cannot find anything about the default value for a OTP?

This is how it looks like on first time launch.

I have tried leaving OTP empty, in addition to trying values 0 and 1, but all i get is an error that says “username/password/token combination is unknown to the system”.

What should the default value be or where should i be able to receive it?
