Set up a digital ID

A digital ID is required to sign a digital signature field in a PDF document and to open PDF documents that others have secured so that only you can view it. A digital ID contains your digital signature as well as information you’ve provided to identify yourself. If you don’t already have a digital ID, you can obtain one from a third-party signature handler, or you can create a self-signed digital ID and share its certificate with others.

To create a self-signed digital ID, choose Document > Security Settings. Select Digital IDs on the left, click Add ID on the right, and then follow the instructions in the Add Digital ID dialog box.
