MySudo has improved the ability for you to receive messages from short codes!
Some internet services use “short codes" for their mass messaging services for verification codes, one-time passwords (OTP), two-factor authentication (2FA), coupon codes, etc.
If a service sends their verification codes, OTPs, 2FAs, etc via a standard phone number, those messages will still be received in MySudo as they always have.
As services change their policies and technology, more short codes from those services will be received.
Please note: Although MySudo does accept messages from short codes, some services, by design, do not accept VoIP phone numbers. Learn more here: I didn't receive a verification code via SMS short code
