18. A method comprising:
receiving, from a first sensor of a first shared system, first information that a first user is proximate to the first shared system;
receiving, from the first shared system, logon information from the first user and first identification information associated with the user in response to receiving the first information from the first sensor;
authenticating, at a logon server, the first user to use the first shared system based on the logon information;
launching a first operating system session for the first user on the first shared system in response to authenticating the first user;
storing, at the logon server, the first identification information;
receiving second information from the first sensor that the first user is not proximate to the first shared system;
suspending the first operating system session on the first shared system in response to the second information from the first sensor, the first operating system session being associated with the first user;
in response to suspending the first operating system session, authenticating a second user to use the information handling system;
launching a second operating system session for the second user in response to authenticating the second user;
suspending the second operating system session;
in response to suspending the second operating system session, receiving, from a second sensor of a second shared system, second information that the first user is proximate to the second shared system;
receiving, from the second shared system, second identification information associated with the first user in response to receiving the second information from the second sensor;
determining, at the logon server, that the first identification information matches the second identification information; and
resuming, on the second shared system, the first operating system session in response to determining that the first identification information matches the second identification information.
