Techniques are disclosed relating to automating permission requests, e.g., in the context of multi-factor authentication. A mobile device may display an option to allow a user to automate responses to future permission requests to perform an action. The mobile device may automatically respond to subsequent permission requests based on at least one automation criterion. The action may include login, transaction approval, physical access, vehicle ignition, account recovery, etc. The automation criteria may include location, acceleration, velocity, wireless connectivity, proximity to another device, temperature, lighting, noise, time, biometrics, altitude, pressure, image characteristics, etc. Disclosed techniques may increase authorization security while reducing user interaction for multi-factor authentication, in some embodiments.
