You want to prevent a user from accessing your phone while you step away from your desk. What should you do?

Configuring a screen lock is the best way to prevent unauthorized access to a phone while you are away from your desk. A screen lock requires a user to enter a passcode, password, or use biometric authentication (such as a fingerprint or facial recognition) to unlock the device. This effectively protects the data and privacy of the user, as it ensures that anyone who attempts to access the phone without the correct credentials will be denied entry.

Having a screen lock in place is crucial in maintaining security, especially in a work environment where sensitive information might be stored on the device. It acts as a first line of defense against unauthorized access.

Implementing remote backup, setting up a remote wipe program, or installing a locator application do not directly prevent physical access to the device while you are away. Remote backup and remote wipe are useful for data recovery and security in cases of theft or loss, but they would not secure the device itself when simply stepping away. A locator application helps track the device's location but does not prevent access. Therefore, configuring a screen lock is the most effective immediate solution to keep your phone secure.
