Frequently Asked Questions
Do I need a webhook to use WhatsApp Login for WordPress?
No. A webhook is optional for WhatsApp Login. It is mainly used for receiving WhatsApp messages. You can configure and use WhatsApp OTP login in WordPress without enabling a webhook.
Which profile should I select in Authentication settings?
Select your primary profile, usually the main admin profile. Even if your website has multiple users, admins, or tenants, WhatsApp login authentication is handled through one selected default profile.
Why do I see a Generate button for the OTP template?
The Generate button appears when your selected WhatsApp profile does not yet have an approved authentication template for OTP messages. It helps you create and submit a default OTP template for approval.
What happens if Use Password Instead is disabled?
If this option is disabled, the Use Password Instead link will not appear on the WhatsApp login widget. Users will only be able to continue with WhatsApp OTP verification.

This option manually syncs previously verified WhatsApp users into your Contacts list and assigns them to the Verified group, helping you keep your contact database updated.
What email is used when a new user logs in with WhatsApp for the first time?
WordPress requires an email address for every user account. If a new user signs in with WhatsApp and does not already exist in WordPress, the system creates a temporary email address using the user’s phone number and your domain. The user can update it later from their profile page.

You can set the OTP length between 4 and 8 digits. A 6-digit OTP is generally recommended because it offers a good balance between security and user convenience.
