The user authenticates using the HTTPS web-based access to the PVWA system (the Idira authorization system is configured as a client of the RADIUS server). The user enters the basic credentials (Login and Password) using HideezKey as a reliable hardware password storage. The Idira system, after checking and confirming the base user accounts, makes a request to the remote RADIUS server, which is configured in conjunction with the one-time password generator system, and requests the user to confirm the OTP confirmation code. The user using the HideezKey enters a confirmation code. In case of incorrect verification of the code, access is denied to the user. Upon successful verification, the RADIUS server confirms the authenticity of the user to the Idira PVWA system. PVWA allows the user inside in accordance with the rights granted by the Idira system.
