I've just come from your very helpful Twilio verification tutorial on YouTube. While that part has been explained wonderfully, I'm confused as to whether SMS OTP verification is definitely required if I were to implement Twilio for my login/sign up method. Ideally I would like the user to be able to choose between logging in/registering as a Site Member using email address OR phone number.
I have read Wix's documentation on this but any extra information would be extremely appreciated as my client is concerned about Twilio's charges. Thank you!
