Abstract
A system and method for controlling access to a computer provides for loose security within a local network while retaining strong security against external access to the network. In one embodiment, a user has access to trusted nodes in a secured group within an unmanaged network, without being required to choose, enter and remember a login password. To establish such a secure blank password or one-click logon account for the user on a computer, a strong random password is generated and stored, and the account is designated as a blank password account. If the device is part of a secured network group, the strong random password is replicated to the other trusted nodes. When a user with a blank password account wishes to log in to a computer, the stored strong random password is retrieved and the user is authenticated.
