Authentication templates are specialized message formats used by businesses to verify user identities through one-time passcodes (OTPs) delivered via messaging platforms like WhatsApp. These templates ensure secure and efficient user authentication during processes such as account verification, recovery, and integrity challenges.

Key Features of Authentication Templates:

• Preset Message Content: The templates include fixed text, such as “<VERIFICATION_CODE> is your verification code,” along with optional security disclaimers and expiration warnings.
• Interactive Buttons: They feature buttons like “COPY_CODE,” which allows users to copy the OTP to their clipboard, and “ONE_TAP,” enabling automatic code autofill within the app. ​

Zero-Tap Authentication Templates

Zero-tap authentication templates allow your users to receive one-time passwords or codes via WhatsApp without having to leave your app.’

One-Tap Autofill Authentication Templates

One-tap autofill authentication templates allow you to send a one-time password or code along with an one-tap autofill button to your users. When a WhatsApp user taps the autofill button, the WhatsApp client triggers an activity which opens your app and delivers it the password or code.

Copy Code Authentication Templates

Copy code authentication templates allow you to send a one-time password or code along with a copy code button to your users. When a WhatsApp user taps the copy code button, the WhatsApp client copies the password or code to the device’s clipboard. The user can then switch to your app and paste the password or code into your app.
