Yes. In fact, it is required, not optional. We believe it is really important in helping protect your account.
We employ Two-Factor Authentication (2FA) while you set up your account and install your sensor (which as you know takes about 2 minutes total). In fact, 2FA is employed if you ever need to reset your password, or decide to change to a different Wi-Fi network (for instance, if you’ve changed internet providers, upgraded your Wi-Fi router, etc.). This thwarts attackers who might otherwise attempt to gain control of your account and reset your password.
