Access control a is way of limiting access to a system or to physical or virtual resources. In computing, access control is a process by which users are granted access and certain privileges to systems, resources or information. In access control systems, users must present credentials before they can be granted access
A more secure method for access control involves two-factor authentication. The person who desires access must show credentials and a second factor to corroborate identity. The second factor could be an access code, a PIN or even a bio-metric reading
