WhatsApp authentication template

How to design and submit WhatsApp authentication templates for OTP/login use cases.

WhatsApp authentication templates are used for OTPs and login flows. They fall under the authentication category and must be concise and secure.

Key takeaways

  • Authentication templates carry OTPs or login codes; no promotions allowed.
  • Clarity and security matter—avoid adding marketing content.
  • Include sample OTP values when submitting for approval.

What to include

  • A short code or OTP placeholder (e.g., {{1}}).
  • Expiration time and instructions if needed.
  • Support contact if the user did not request the code.

Best practices

  • Keep it brief and avoid links unless necessary.
  • Do not mix promotions or upsells—stay purely transactional.
  • Use numeric placeholders and clear sample values.

Example copy

  • “Your verification code is {{1}}. It expires in 10 minutes.”
  • “Use {{1}} to log in. If you didn’t request this, reply STOP.”

FAQs

Can I add marketing to an authentication template?

No. That would violate policy and likely get rejected. Keep auth templates purely for verification.

Do I need opt-in for OTPs?

OTP flows are usually user-initiated via login/checkout; ensure you still respect user consent and security.

Can I localize OTP templates?

Yes, submit localized versions per language to avoid user confusion and rejections.
