At the core of wireless locks is the ability to connect to smartphones and other smart devices via Bluetooth or Wi-Fi. This connectivity allows users to control their locks remotely, offering a level of convenience that traditional locks simply cannot match. However, the true strength of these locks lies in their security protocols. Multi-factor authentication (MFA) is a critical feature that adds an extra layer of protection, ensuring that only authorized users can gain access.

Multi-factor authentication works by requiring users to provide two or more verification factors to access the lock. This could include something they know, such as a password or PIN, and something they have, like a smartphone or a biometric identifier. For instance, when a user attempts to unlock a wireless lock, they may enter a unique code on their smartphone app. Once this code is verified, the system may then prompt them to use a fingerprint scanner or facial recognition feature on their device. This two-step process significantly reduces the likelihood of unauthorized access, as it requires multiple forms of verification.
