Issue

The Submit button on the Multi-factor authentication login page does not respond when clicked.

Symptoms and Impact

After updating to Pega Platform 23.1.3, when user credentials are entered on the MFA login screen, a prompt appears, requiring a one-time password (OTP). However, after submitting the OTP, no response is returned, and the MFA and login cannot be completed. 

Steps to reproduce

1. Navigate to the username and password input fields in the Pega Platform 23.1.3 login screen.
2. Enter credentials and click Log in.
3. A prompt is displayed requiring an OTP.
4. Enter the correct OTP and click Submit.

Result: The Submit button does not respond and the MFA login cannot be completed.

Root Cause

A defect in Pega’s code or rules modifies the HTML code on the Multi-factor authentication OTP screen leading to issues with the Submit button functionality.
