SmartDialog’s messaging services include SMS verification, which enables reliable user authentication in online services and applications. SMS verification uses SMS messages sent via API.
Two-factor authentication (2FA, MFA) uses at least two different methods to authenticate a user. Typically, the first authentication method is a username and password, in addition to which MFA authentication requires the user to verify their identity using a second authentication method.
SmartDialog’s SMS verification is a service that enables two-factor authentication, in which the user receives a one-time authentication code via text message during login or other authentication (OTP password). The user enters the code into the online service or application form and gains access to the service. SMS verification can also include an API for code verification if authentication validation cannot be performed within the online service.

Send Code API: Sending Authentication Code During Online Login
Text message verification is used in two-factor authentication when logging into an online store or other online service. In addition to primary authentication, the user is directed to request a code to their phone.
Send Code API automatically generates the unique one-time code required for two-factor authentication and sends it to the requested phone number. The user can log in by entering the code into the service.
Verify Code API: Sending Authentication Code and Verifying Code Validity
Text message verification is used in two-factor authentication when logging into an online store or other online service. In addition to primary authentication, the user is directed to request a code to their phone.
Verify Code API generates a unique one-time code and sends it to the requested phone number. The user enters the code into the service, whereupon the Verify Code service verifies whether the provided code is correct, allowing the user to log in.

SMS authentication is an authentication method that uses a one-time code sent by SMS to verify the identity of the user.
In SmartDialog, SMS verification is part of the two-factor authentication (2FA/MFA): the user first logs in with a username and password, for example, then receives a one-time code (OTP) on their phone via SMS, which is entered into the service to confirm authentication.
The service can be implemented with APIs that automatically send and check the code.
In practice, this is how SMS authentication works:
In SmartDialog, this is done through interfaces such as the Send Code API and Verify Code API, which take care of generating, sending and verifying code.
