Proximity Authentication Definition: Proximity authentication verifies a user's identity based on the physical proximity of a device or token to a system or network, using technologies such as Bluetooth or RFID.
Proximity authentication is a security method that allows access to a system, device, or application based on the physical proximity of an authenticated entity, such as a smartphone or token, rather than traditional methods like passwords or biometrics. This technology typically utilizes Bluetooth, NFC (Near Field Communication), or RFID (Radio Frequency Identification) to establish the proximity of the authenticated device for granting access privileges.
