  • Patent number: 11354396
    Abstract: Methods, systems, and computer readable media for authenticating to a computer system. In some examples, a method includes receiving a request from a user device for authentication, the request specifying a username. The method includes determining grid information associated with the username by accessing a repository of grid information for usernames, the grid information specifying a color set. The method includes sending the color set to the user device, causing the user device to display a grid of colored tiles, each colored tile having a color specified by the color set. The method includes receiving a sequence of tile selections from the user device, each tile selection specifying a user selection of one of the colored tiles. The method includes granting or rejecting the request for authentication based on the sequence of tile selections and the grid information associated with the username.
