Authentication Templates in WhatsApp Business API

Authentication messages are essential for businesses to securely verify users through one-time passcodes (OTPs), often at multiple steps in the login process. Authentication templates are specifically used for account verification, password recovery, and security challenges to ensure user safety.

Key Elements of Authentication Templates

When sent via the WhatsApp Business API, authentication templates include:

Fixed Preset Text – Example: “<VERIFICATION_CODE> is your verification code.”
Optional Security Disclaimer (Example: “For your security, do not share this code.”
Optional Expiration Warning – Example: “This code expires in <NUM_MINUTES> minutes.”
Button Options – Businesses can include a one-tap autofill button, a copy code button, or no button (for zero-tap verification).

Strict Regulations for Authentication Templates

Authentication templates are the most strictly regulated among all template types. Businesses must adhere to the following restrictions:

No URLs, media, or emojis are allowed in authentication templates.
Parameters must be no longer than 15 characters to maintain clarity and security.
Content must remain concise to prevent misuse and ensure a smooth verification process.

These regulations enhance security by keeping authentication messages clear, professional, and tamper-proof.

The Importance of Authentication in Digital Communication

In an era of increasing digital transactions, securing user accounts and sensitive data is crucial. Authentication templates build trust by ensuring safe and verified communications between businesses and customers.

These templates are commonly used for:

OTP Verification – Secure logins and account access.
Account Recovery – Password reset or account restoration.
Secure Login Alerts – Notification of login attempts or suspicious activity.

Best Practices for Authentication Templates

User-Friendly Language – Use simple and direct messaging for easy understanding.
Clear Instructions – Guide users through the verification process with step-by-step clarity.
