Methods, systems, and devices for process verification are described. An authenticator application of a device may receive, from an authenticating application of the device, a first request to establish a network connection between the authenticator application and the authenticating application. The first request may identify a port associated with the network connection. The authenticator application may receive a second request from the authenticating application to authenticate an identity of a user. The authenticator application may identify a process used to establish the network connection between the authenticator application and the authenticating application on the port. The authenticator application may obtain a signature and a set of data associated with the signature based on the identified process. The authenticator application may authenticate the identity of the user based on the signature and the associated set of data.

Caller process verification for device-bound authenticators

An authentication system supports multi-factor authentication (MFA) when authenticating the identity of a user. A challenge-response portion of the authentication process is delegated to an MFA device-a secondary device within control of the user, but separate from the primary login device that the user is using when initiating the authentication. Communications between the MFA device and the login device are conducted using a short-range wireless communication protocol (e.g., Bluetooth™ or NFC), so that the two devices must be in close physical proximity to each other.
