# Specify a default ID

Specify a default ID so that you aren’t prompted to provide one each time you sign a PDF.

1. Choose Document > Security Settings.
2. Select Digital IDs on the left, and select the desired digital ID on the right.
3. Click Usage Options, and specify when to use the digital ID.

Set only one digital ID for each usage so you don’t have to choose an ID later.
