We will be making modifications to how signers are authenticated when the SMS authentication configuration is enabled by senders in Box Sign.
When SMS authentication is enabled, signers are not prompted to authenticate themselves until the end of a signature request when they've completed all the required fields assigned to them. We will be modifying the signer authentication workflow to require signers to authenticate themselves via SMS authentication before they gain access to view, fill, and sign the signature request. This modification will align with industry standards and other signer authentication workflows within Box Sign like Box account login and password authentication.
