Authentication templates exist for a single job: sending verification codes for logins, account recovery, and transaction confirmation. They are a WhatsApp alternative to SMS one-time passcodes.
WhatsApp provides a dedicated format for these templates, including a copy-code button, and applies content rules so they cannot be used for marketing.
They are priced in their own authentication category, separate from marketing and utility. Rates differ by country, so businesses comparing WhatsApp to SMS for verification should check the local pricing.
