# SMS as an MFA factor

Multi-factor authentication \(MFA\) with SMS as a factor for your authentication.

Admin can configure ServiceNow instance to require users who attempt to log in to the instance using SMS-based OTP.

When users attempt to log in to ServiceNow, SMS OTP is sent to the mobile number associated with the sys\_user record. Users can enter the six-digit verification code that it sent to the mobile device and verify their identity.

You can configure MFA with SMS using the default Twilio as well. For more information, see [Multi-factor authentication providers](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/platform-security/authentication/multi-factor-authentication-providers.md).
