Change the signing method

You may need to specify a different signing method than the default security method provided in Acrobat.

  1. If necessary, install a third-party signature provider.
  2. Choose Edit > Preferences (Windows) or Acrobat > Preferences (Mac OS), and click Security on the left.
  3. Click Advanced Preferences, and click the Creation tab.
  4. From the menu in the Creation tab, choose the default method you want for signing and encrypting documents, and click OK.

    The menu lists all the security methods installed in the Acrobat plug-ins folder.
