Validate a user by password in perspective

In vision I can validate a user by password by using **system.security.validateUser(username, password, authProfile, timeout)
In perspective is the other hand, the system.perspective.isAuthorized() can’t check the current login user password.
I need this because after a user login in the system, I want each time the user want to send dangerous command, he is recheckef by the his password. In this way other operator which seat there can’t send the command if the current login operator left the control room for just a minute.(for example go-to WC)
The system.perspective.isAuthorized() can’t get the current user password again to validate it.
Is there any way to do this right now in perspective? for example access user password in session props.
