supports Digital Signatures. Authenticated users can digitally sign a section, lock it down and prevent tampering with the data. Sections in forms/flows can be signed using a text rendering of the user's name (user credentials) or a previously uploaded signature image. The user must be be authenticated to the Server.  Another alternative is to use Wet signature capture. A wet signature is a signature that is entered or created at the time of form entry.  Wet Signatures make it possible for the user to enter the signature using either a track pad/mouse, stylus or a touch screen in use mode. This feature becomes very important when designing for Mobile devices. Refer to the PageBreak control for more information on mobile forms.

Both authenticated and non-authenticated users may sign a form using a wet signature. If authentication is required, Signed Sections should be used.

No special hardware is required. All you need is a smartphone or a computer with a browser that supports HTML5. View this video about Electronic Signatures feature.

The default value is None Required. The Must sign property makes the signature required. With Must sign, a form cannot be submitted or a workflow is not sent to the next person until the signature is added. Lock sign means that the next person in the workflow can not remove the signature and edit the signed data. A good use case is an employee performance review where the manager starts the form, and signs the review, and sends it to the employee. You would check Lock sign so the employee cannot unsign and edit the data entered by the manager.

Checking Must Sign will disable the None Required option from the Signature dropdown and automatically selects Text/Signature Image. You can change the Signature dropdown to Wet Signature 

Sections that are hidden/not hidden via a rule or the Visible property in the designer, behave as stated below with respect to Must Sign:
