An application for dynamic, granular access permissions can include a database interface, a user interface, a login process, an administrator, an event handler and an authorization process. The database interface can be an interface to an access control permissions database that stores roles, actions, or policies for users of the application. The login process can authenticate a user and determine a default set of access control permissions for that user when they are using the user interface. The administrator can provide access control permissions for a user by using the database interface. The event handler can dynamically modify access to functionality in the user interface based on an event. The authorization process can determine whether a request from the user interface is authorized before process the request. The authorization process can use access control permissions from the administrator and either a scope limited or a temporally limited access permission.
