When I follow this steps, I can't get the last one done as it specifys on the guide. It sends me to selec a file. Where do I choose the digital ID?
To avoid being prompted to select a digital ID each time your sign or certify a PDF, you can select a default digital ID.
A check mark appears next to selected options. If you select only the signing option, the Sign icon appears next to the digital ID. If you select only the encryption option, the Lock icon appears. If you select only the certifying option, or if you select the signing and certifying options, the Blue Ribbon icon appears.
Note: To clear a default digital ID, repeat these steps, and deselect the usage options you selected.
