WhatsApp Authentication templates help businesses authenticate users with one-time passcodes, typically comprising 4-8 digit alphanumeric codes. These codes are utilized across various stages of the login process, including account verification, recovery, and integrity challenges. Sample messages include:
- {{1}} is your verification code.
- {{1}} is your verification code. For your security, do not share this code.
- {{1}} is your verification code. This code expires in 15 minutes.
Best Practices
To optimize OTP usage for WhatsApp:
- Confirm the user's WhatsApp phone number before sending the one-time password or code.
- Clearly communicate to the user that the password or code will be sent to their WhatsApp phone number, especially if multiple delivery methods are available. For additional guidance, refer to the "Getting Opt-In" article.
