Recently, the number of users sharing smartphone passcodes has increased. The management team wants a technician to deploy a more secure screen lock method. Which of the following technologies should the technician use?

Pattern locks are relatively easy to bypass, as they can be observed by someone watching the user or can be inferred from smudges on the screen. Additionally, users often create simple patterns that can be guessed, making this method less secure compared to biometric solutions like facial recognition.

While device encryption is crucial for securing data at rest, it does not serve as a screen lock method. It protects the information stored on the device from unauthorized access but does not prevent someone from accessing the device itself. Therefore, it is not a direct solution for enhancing screen lock security.

Multifactor authentication (MFA) enhances security by requiring multiple forms of verification, but it is typically used for accessing accounts or services rather than acting as a screen lock. While MFA is beneficial for overall security, it does not specifically address the immediate need for a more secure screen lock method.
