Abstract: Systems, methods, and software technology for providing access control with respect to bots is disclosed herein. In an implementation, an access control service monitors a location of a device with respect to a geographic area. In response to when the device has entered the geographic area, the service grants a bot associated with the geographic area with access to the device. The service may grant the bot with continued access to the device if an end-user conversed with the bot while it had access. However, the service may deny the bot the continued access to the device if the end-user did not converse with the bot.
