SMS-based one-time passwords (OTPs) are a security mechanism that utilizes text messages sent to a user's mobile device to provide a temporary, single-use authentication code. This method enhances security by adding a second layer of verification beyond traditional passwords, commonly used in two-factor authentication (2FA) systems to confirm user identities during login or transaction processes.
Key Features
- Utilizes SMS messaging for delivery of OTPs
