Authentication
Setup OTP
Configure phone-first login, OTP delivery, country picker behavior, and profile completion.
OTP flow
Commerce Auth supports phone-first login with a custom modal, country picker, verification flow, and profile completion steps.
OTP delivery can run through the current WhatsApp engine or SMS providers depending on your configured delivery settings.
Profile rules
You can require users to complete missing profile details before they continue through checkout or account flows.
Email can remain optional while phone stays the identity anchor for the customer.
