Twilio requires Authy for 2fa for sendgrid and maybe even twilio itself instead of supporting more standardized 2fa that’d allow 1pass to be used. This is all the more frustrating because I was forced to use Authy to protect an account instead of my regular tooling and they still managed to screw it up. Twilio, take a hint and stop forcing people to use your custom thing
