Device binding links a user’s device directly to their account, so only that specific device can be used to authenticate. This ensures that even if someone tries to log in remotely using stolen credentials, they won’t succeed - because they would need the actual device to gain access.

If a fraudster steals a user’s login credentials, they can’t simply log in from another device. Without the original device that was bound during sign-up, access is denied, stopping remote login attempts before they can happen.

Device binding is crucial for preventing unauthorized access and meeting Strong Customer Authentication (SCA) requirements. By binding a user’s device, systems can verify that the access attempt is coming from a trusted, known device - eliminating the risks associated with easily shared credentials or one-time codes.

When combined with biometric face authentication, secure device binding delivers an even higher level of protection. Each login requires not just a recognised device but also a live biometric check, verifying that the person using the device is the legitimate user. This dual-layer approach prevents impersonation and adds robust identity assurance without compromising on user convenience.
