Systems and methods for detecting interception devices. In some aspects, the system causes transmission of a first detection signal. Based on receiving a first response signal, the system determines a first probability of detection of a first interception device. Based on the first probability of detection, the system transmits a first command to deactivate a user authentication interface. The system may cause transmission of a second detection signal and determine a second probability of detection of a second interception device. In response to the second probability, the system may transmit a second command to reactivate the user authentication interface.
