Pega® Platform now supports two-factor authentication in custom authentication services and case flow processing, by sending a one-time password to an operator through email and requiring the operator to provide it back to your application for verification. Use REST API OTP Generation to generate and store one-time passwords, and REST API OTP Verification to verify passwords against user entries. You can also use the pxSendOTP and pxVerifyOTP activities called by these APIs to implement two-factor authentication of users in case flows prior to performing a critical operation (e.g. before completing a critical transaction such as a funds transfer in excess of a certain amount). Settings on the Security Policies landing page control the behavior of the two-factor authentication process.
