Device binding links a user’s device to their account, ensuring only that device can authenticate the user and reducing unauthorized access risks. It proves the user has the specific linked device, preventing the use of other devices for authentication and restricting account access to designated devices.

A required component of Strong Customer Authentication (SCA), this process significantly enhances security by making sure only trusted devices can access an account.

To bind a new device, instead of using costly SMS OTPs or call centers, Keyless uses a biometric selfie, making the process easier and more secure. This way, only the original user's face can authorize new devices, eliminating the need for re-enrollment. The process involves showing biometrics to both the new and the old device, ensuring proximity and ownership, and maintaining high security standards.

This method ensures that the transition to a new device is seamless and secure, maintaining the integrity of the account without compromising on convenience.
