OTP Verification

Deliver one-time passcodes on WhatsApp your users already trust. This category covers authentication end to end: registration and login codes, password resets, phone verification, resends, and sensitive account-action confirmations. Each scenario ships with 1MSG Business API code using Meta-approved authentication templates, so codes arrive instantly and reliably. Built by an official WhatsApp Business API provider — a faster, higher-trust alternative to SMS for verifying real users.
