How do I use the device lock on my Fitbit device?

Turn on the device lock and set a personal 4-digit PIN code to help keep your Fitbit device secure. This feature is available on watches and trackers that support contactless payments.

To help keep your Fitbit device secure, turn on the device lock in the Fitbit app. You'll be prompted to enter a personal 4-digit PIN code to unlock your device. If you set up Fitbit Pay or Google Pay, the device lock is turned on automatically and you’re prompted to set a code.
