Frequently Asked Questions

Why is the Signatures category missing from my Acrobat preferences?

The Signatures category is typically only available in the fully-featured desktop version of Adobe Acrobat. If you are using a mobile application or the web browser extension, this settings menu is deliberately omitted.

What is the difference between a self-signed digital ID and a certified one?

A self-signed digital ID is created locally by the user and is best for personal use or internal business workflows. A certified ID is issued by a trusted third-party Certificate Authority (CA) and is required for legally binding external documents to independently verify the signer's identity.

Where is my self-signed digital ID saved on my computer?

By default, Acrobat saves your newly created self-signed digital ID as a .p12 or .pfx file in your user profile directory. You will be prompted to choose the exact save location and set a required password during the creation process.
