This is the first step for authentication with a mobile number.
Start the authentication process by providing your mobile number. A TOTP code will be
sent and then you can verify your mobile number with the TOTP code to complete authentication.
Note: not all mobile numbers will work for authentication with Parrot. For now please use
a mobile number from North America. We'll be expanding access soon!
