Techniques are disclosed for restricting access to resources accessible in a SSO session. An access management system may provide access one or more resources by implementing an SSO system to provide a SSO session. An SSO session may provide an authenticated user with access to protected resources to which the user is entitled to access. In some instances, a user sharing a computer with other users may want to access a particular protected resource so as to restrict other users sharing the computer from accessing other protected resources accessible to the user in an SSO session. The access management system may enable the user to dynamically choose, such as during login, the protected resources which to restrict and/or permit. Upon successful authentication, a session may be established for only those protected resources that are permitted based on the user's selection, while the other resources are restricted.

The invention discloses an access control method and system, an electronic lock, and a management and visitor terminal. A management terminal authorizes the access of a legal visitor terminal to an electronic lock.
