how can i implement two step registration with phone number in django?

Question

I'm trying to make a django app that needs to implement two-step registration with phone number and i searched for it and i did not find a useful result.

I have this idea that take a phone number and then generate random hash URL then redirect them into it for registration. is that good implementation?

and if you have a better idea for doing this please help me.

and sorry for my bad English.
