What is a WhatsApp authentication template?
A WhatsApp authentication template is an approved message format that delivers a verification code to confirm a user’s identity or account action. It supports login, registration, password recovery, device verification, and transaction-security workflows.
Authentication templates are different from marketing messages because their purpose is secure verification rather than promotion.
How does it work?
When a customer performs an action that requires verification, the business generates a temporary code. The code is sent using an approved authentication template, and the customer enters it into the relevant application.
A secure implementation should include:
- Code expiration
- Attempt limits
- Replay protection
- Secure code generation
- Delivery monitoring
- Fraud detection
- Fallback channels
- Data protection
For example, an Indian fintech application may send an OTP through WhatsApp when a customer signs in from a new device. The message should contain the code and only the information required for verification.
Businesses comparing WhatsApp with SMS should review WhatsApp versus SMS for OTP and consider reach, delivery, security, consent, cost, and fallback requirements.
Common use cases
- New-account registration
- Login verification
- Password recovery
- Device verification
- Transaction confirmation
- Contact-number verification
- High-risk action approval
Authentication versus marketing templates
An authentication template confirms identity or access. A marketing template promotes a product, service, or offer.
Authentication messages should not include unrelated promotions. Keeping the message focused improves clarity and supports the customer’s immediate task.
