A template for delivering one-time passcodes and verification codes over WhatsApp.
An authentication template is a WhatsApp message template in the Authentication category, used specifically to send one-time passwords (OTPs) and verification codes. These templates follow a constrained format designed for security, often including a copy-code button so users can paste the code with one tap.
Authentication messages help businesses verify logins, confirm transactions, and secure account changes. Because they are time-sensitive and security-related, they are kept simple and cannot carry marketing content.
WhatsApp authentication is popular as an SMS alternative because delivery is reliable, the experience is seamless, and in many markets it can be more cost-effective than SMS OTP.
WhatsApp OTPs offer a faster, often cheaper, more reliable alternative to SMS for logins and transaction verification.
