When you create a transaction and add one or more recipients, you can set additional options for each individual signer. By moving your mouse on the receiver, a gear will appear on the right.
If you click on the gear, you will enter the screen below.
Under "Authentication" you can choose to add an additional authentication method. An email is always sent by default for signature. In addition, there is the option to send an extra SMS code or apply Q&A. During the SMS verification, a code is sent to the mobile number of the recipient. The recipient will have to enter this code to sign. The SMS functionality is only available when an SMS bundle has been purchased.
Q&A stands for Question & Answer, where at least one Q&A is required to be entered. Q&A allows you to submit questions to the signatory; in this case they are 'shared secrets'. You can formulate questions based on information you already have about your customer, such as the last four digits of his / her Social Security number or an ID number. If the signer provides the correct answer, it will be verified as the correct recipient of the transaction. This Q&A function is ideal when, for example, sending an insurance claim or an electronic transfer.
