When creating a registration token for an Azure Virtual Desktop host pool, what is the minimal duration for the token's validity period?

The minimal duration for the registration token's validity period in an Azure Virtual Desktop host pool is indeed 1 hour. This is important as the registration token is utilized when a virtual machine (VM) is joined to the Azure Virtual Desktop environment. The token ensures that the VM is authorized to communicate with the Azure Virtual Desktop service and register itself as a session host.

Setting the validity period to 1 hour strikes a balance, granting sufficient time for deployment and registration processes while also maintaining security by preventing long-lived tokens. Since the registration process involves several steps, from VM provisioning to joining the host pool, having at least an hour allows for those processes to complete effectively.

This hour-long validity helps administrators manage the lifecycle of VMs securely and efficiently while limiting the window for potential unauthorized access, aligning with best practices in cloud security.
