NOTE:

To add this product to your account, contact a Telesign expert. This product is available for full-service accounts only.

Telesign SMS Verify delivers phone-based verification and multi-factor authentication (MFA) using a limited duration, one-time passcode (OTP) sent over SMS.

Common use cases:

  • Multi-factor authentication (MFA) - Send an OTP to a user's phone number, to complete a log-in process after they have entered their password.
  • Password reset - Send an OTP to a user's phone number to verify their identity before they reset their account password.
  • Phone number verification - Send an OTP to a phone number provided by a user to verify their ownership of the number.
  • Account update: Send an OTP to a user's phone number to validate critical interactions such as high-value transactions, account updates, and money transfers.

NOTE:

An SMPP implementation may offer better throughput than the REST API, but the integration requires a higher level of technical expertise and may take longer.
