Generating and installing user certificates

You can generate and install a user certificate for client authentication and code signing in your Windows machine, if you have the admin role.

Client authentication

Client authentication enables mutual TLS (mTLS) authentication between the Unattended Robot application and the ServiceNow server while making a connection.

You can either generate and install user certificates or export active directory certificates.

Code signing certificate

A code signing certificate is used for signing and verifying the automation packages from RPA Desktop Design Studio. This certificate detects any tampering or corruption of scripts before they're run.

The code signing certificate is validated during the Unattended Robot and Attended Robot executions.

If you don't have the active directory certificates, do the tasks in the following topics to generate and install user certificates. For more information, see Exporting Microsoft Active Directory certificates.
