Control all your devices
Lock, ring or remove any device, and use your phone as a master key.
Steps
Open Devices to see every phone, computer, browser and extension on your account.
Choose Lock on one device, or Lock all my other devices. On a computer you can also lock the screen; on a phone you can make it ring.
Lost a device? Choose Remove. It is signed out at once and erases what Passkey-X kept on it the next time it connects.
In the Android app, turn on Use this phone as my master key. Your phone can then approve new sign-ins with matching numbers and unlock your computers.
Optional: turn on Lock my computers when my phone is away (with Presence on in the phone app), and Require my phone to approve new sign-ins.
