Secure the device you carry
Mobile security
Lock down phones, apps, permissions, messages, backups, and the plan for a lost device.
The big picture
Protection works in layers.
Your phone is an identity token, wallet, camera, archive, and password-reset device. Its strongest protection comes from a current operating system, a strong lock, restrained permissions, and a recovery plan set up before loss.
A phone connects account recovery, personal privacy, and nearly every security tool used throughout the day. Explore Identity theft protection, Online privacy & data control, and Cybersecurity tools & services.
