Verification code via Email

Last updated: August 11, 2025

The OTP via Email Login feature allows your customers to sign in without using a password. Instead, they receive a secure, one-time passcode (OTP) directly in their email inbox.

This approach removes the need for customers to remember passwords and makes logging in fast, secure, and mobile-friendly. It also works for both new and returning customers — new users can create an account right after verifying their email, while existing users can sign in instantly.

Merchants can set up and manage all aspects of this feature directly from the Studio dashboard without any coding. The feature supports multiple email providers, customizable templates, and security controls to ensure a smooth and safe experience for customers.

Troubleshooting / FAQ

1. Customers are not receiving the OTP email.
