Abstract
A computer system receives a request to access a server. The request includes a first device tag set. When the first device tag set matches a previously assigned device tag set, the computer system allows access to the server without requesting full access credentials of a user. The computer system invalidates the first device tag set, and sends a second device tag set. When the first device tag set does not match the previously assigned device tag set, the computer system requests full access credentials from the user.
