Privileged Session Manager (PSM) is an application cluster used to access, record, and monitor privileged sessions. It can be hosted as a Docker Swarm on local or cloud service locations. It launches when users with Login Session Access to a managed computer check out the credentials for that computer. You can configure PSM to record session activity, allowing Access Managers and other administrators to view what users do on the computer during a session.

This walks you through the process of setting up PSM. To completely set up PSM, you need to do the following:

1. Install Docker and Docker-Compose on a Linux server. The Linux server is the PSM server.
2. Create an OAuth application for PSM in EmpowerID.
3. Configure EmpowerID System Settings for PSM.
4. Generate a X509 certificate for the PSM OAuth application and upload it to the local machine and EmpowerID certificate stores.
5. Create a service account (EmpowerID Person) for PSM and map the certificate to that service account.
6. Use OpenSSL to extract the private and public key from the certificate.
7. Create Docker secrets on the PSM server.
8. Copy the psm.yml file you receive from EmpowerID to the root directory of the Linux server.
9. Initiate Docker swarm mode on the Linux server.
10. Pull the PSM Docker images from Dockerhub.
11. Deploy the stack.
