So, it’s a simple way of blocking the access of any unauthorized user. Even if someone manages to steal the device, unless he is knowledgeable enough to crack the PIN, the Fitbit smartwatch will be useless for him.

The PIN will be enabled every time the user puts up the wearable on his wrist. Also, for e-payment, some merchants may request the user to enter the 4-digit PIN to authenticate a transaction.
