Hello,
During the Self-Service Password Reset from the Windows Logon Screen, the actual process of password reset is performed via Adaxes Web Interface. All security-sensitive information is encrypted using the RSA encryption mechanism with a 1024-bit key.
Since Adaxes Web Interface is an IIS web application, you can additionally enable SSL for the Web Interface in order to improve security. Since, Self Service Client and Direct Access, you are going to expose the Web Interface to computers located outside of your on-premises network, we would recommend enabling SSL for the Web Interface. This can be done the same as for any other IIS web application.
