A computer-implemented method for managing access-control settings may include identifying an initial access-control setting that controls a user's access to a computing resource. The method may also include displaying, via a graphical user interface, a representation of the computing resource. The method may further include receiving input that resizes the representation of the computing resource from an initial size to a new size, detecting the new size of the representation of the computing resource, and modifying the initial access-control setting to establish an updated access-control setting that corresponds to the new size of the representation of the computing resource. Various other methods, systems, and computer-readable media are also disclosed.
