What Is SMS Authentication?

A phone authentication service verifies users with a text message. The message typically contains a 4-digit code.

Text authentication done through OTP or TOTP adds an extra verification factor. For signups, you can use email and SMS to avoid spam registrations.

Trending Use Cases of SMS Authentication

New Registrations

Send your new customers a one-time SMS passcode to make sure they’re real people.

SMS Authentication Usage

An Essential Service

Many industries require SMS authentication on a daily basis. Websites that need to verify their users the most deal with online registrations, financial transactions, or sensitive private information.

SMS authentication is also necessary to verify a user’s identity on social networks. This way, authentication services prevent fake and fraudulent accounts from registering. Similarly, retail stores also use SMS authentications to provide users access to a loyalty program or confirm a coupon or discount.
