This article will help you if you want to know how to connect your Withings device to your Wi-Fi network when using a two-factor authenticator (2FA)

A connexion via a 2FA network is not possible with the Health Mate app. However, the communication to our servers uses an end-to-end encrypted communication channel (TLS protocol) for all devices since Smart Body Analyzer (2013). It means you can safely connect via any WEP, WPA, or WPA2 network.

Note: Public hotspots requiring an extra step or password are considered 2FA networks.
