Enable Phone OTP Login

Feature Description

In addition to email and password login, you can enable Phone OTP Login for your Shopify users. When enabled, users can log in securely using a one-time password (OTP) sent to their registered phone number via SMS, removing the need for passwords. This offers a quick and secure authentication method, making it ideal for customers who prefer fast, passwordless access via their mobile devices.
