'How many hours of work to integrate auth0 login and registration?

I'm wondering how many hours of programming time it should take using auth0's API to integrate auth0 login and registration from start to finish into an existing website.

I was expecting 10-20 hours max. Is this a correct range? Or should it take less or more time?
