Email is considered insecure as a 2nd factor. TOTP stands for Time-based One-Time Password. Usually you store a seed and that combined with the time generates a time based password. If someone intercepts it, it’s only valid for a certain time frame (I think about a minute or so), after which it’s invalid.
What’s the 2nd factor? Email and what else?
