Phone Authentication

Phone Registration

With LoginRadius, you can give your customers the flexibility to use their phone number to login to your website and apps.

How does Phone Registration Work?

With phone registration, customers use their number to identify themselves. This occurs in three simple steps:

  • The customer fills out the registration form with their phone number.
  • LoginRadius sends a code via SMS or automated call asking the customer to verify their phone number.
  • The customer authenticates by entering the code. LoginRadius then automatically creates a profile and allows the user to log in.

International Coverage

The LoginRadius phone registration service has worldwide coverage to ensure that you can serve your customers no matter where they are.


The LoginRadius phone registration service is designed to work seamlessly with mobile apps and automatically detects the verification SMS code to deliver a frictionless experience for your customers.

One Time Password (OTP) Support
