Two-factor authentication availability

Two-factor authentication is explicitly mentioned as available for account access, adding protection for cloud-connected control and sharing features.

Two-factor authentication and account verification (email/phone codes) are highlighted as strong protections in several reviews, helping reduce the risk of unauthorized remote control.

The app includes optional verified access that requires phone biometrics or a passcode before operating the lock, adding a practical extra layer of protection against unauthorized use of an unlocked phone.

At least one review describes multi-step account or device activation verification (codes via SMS and email), indicating stronger account protection than many simple Bluetooth locks.

Several reviews describe a PIN requirement for voice unlocking, adding an extra layer of protection. Some also raise usability or privacy concerns about speaking a code aloud.

At least one review explicitly criticizes the companion app for lacking two-factor authentication, even while other reviews mention phone-number verification during account creation. If account security is a top priority, this is a notable weakness compared with platforms that offer robust 2FA.

At least one review criticizes the Schlage app for lacking two-factor authentication. Security-conscious users may see this as a weak spot for an account-connected device.
