Would rather use authenticator for 2fa. I beleive it's more secure.
In production! Make sure you're on the latest app and check the Settings -> Security page 💪
Consider generic 2FA support too. I use Authy myself in an effort to move away from the Google ecosystem
@Jean Amiouny: implementing both the FIDO standard U2F and/or HMAC-based OTP options would be a great way to lead in this space regarding security.
@ǝpɐɥsʇɥƃᴉu ⋰·⋰: TOTP-based 2fa is now in production. Would love your feedback.
