Obtaining a digital ID from a third party
In general, digital IDs are issued by a third party for use in any official capacity. Third-
party providers, such as Entrust, include advanced security features. The provider of
digital ID certificates is sometimes called a certificate authority or a signature handler.
Third-party providers verify your identity, issue the private key, protect the public key,
and maintain system integrity. You may want to obtain more than one digital ID if you
sign documents in different roles or with different certification methods. See the Adobe
website for information on using providers with advanced security features.

1. Choose Advanced > Security Settings.
2. Select Digital IDs on the left.
3. Click Add ID.
4. Select Get A Third-Party Digital ID, click Next, and follow the instructions on the web
page that appears.
To specify a default signing method:
1. Choose Edit > Preferences (Windows) or Acrobat > Preferences (Mac OS), and then
select Security on the left.
2. Click Advanced Preferences, and select the Creation tab.
