Use Fitbit and Smart Lock to Unlock Your Android Phone
Android users got quick unlock features when Smart Lock capabilities were introduced in Android Lollipop 5.0 OS. Smart Lock added several new locking and unlocking methods, and it also improved on the previous facial recognition feature offered in earlier versions of the OS. It can use a trusted Bluetooth device’s presence to unlock a phone.
Here’s how to set up Android Smart Lock to use a Fitbit (or any trusted Bluetooth device) to unlock a phone.
Enter your password or pattern for your device. If you don’t have one yet, open Settings, then go to Security > Screen Lock. If you are creating a password, go to the Screen lock type section, and choose between Pattern, PIN, or Password for a Screen Lock. Using Swipe doesn’t allow you to set up Smart Lock. To use the Smart Lock feature with a trusted Bluetooth device, make sure Smart Lock is turned on. Go to Settings > Security > Smart Lock. You are prompted to enter your chosen Pattern, PIN, or Password before proceeding. Select On-body detection. Toggle Use On-body detection on. In the Keep in mind dialog box, select Continue. Return to the Smart Lock screen and select Trusted devices. Select the + (Plus sign) next to Add trusted device. Select your Fitbit. If you don’t see your Fitbit, you may need to enable Bluetooth or re-sync the Fitbit. Confirm the addition of your Fitbit as a trusted device by selecting Yes, Add.
Remove a Trusted Bluetooth Device in Smart Lock
When you no longer want to use the trusted Bluetooth device, turn off Smart Lock.
Go to Settings > Security > Smart Lock. Enter your passcode and select Next. Select Trusted devices. Select your Fitbit. Select Remove Trusted Device.
Unlocking your smartphone with a Bluetooth device can increase the risk of unauthorized access. For example, if you’re in a meeting in the room next door to your office and your phone is left unattended on your desk, someone could access it without the passcode because your paired device—your Fitbit, watch, or other paired Smart Lock-trusted device—is within range for it to unlock the phone.
