Solution 1Recommended

Use Supported Digital IDs from the Adobe Approved Trust List

A physical REAL ID cannot be directly used as a digital certificate. You must use a supported digital ID from an approved provider.

Physical identification cards, such as a government REAL ID or standard driver's license, do not inherently contain the cryptographic keys required for digital signatures in PDF software.

To digitally sign a document in Adobe Acrobat, you must obtain a digital certificate from a provider listed on the Adobe Approved Trust List (AATL) or use a cryptographic file (like a .pfx or .p12 file).

1
Open Adobe Acrobat Trust settings

Launch Adobe Acrobat Reader DC, go to 'Edit' > 'Preferences', and select the 'Signatures' category from the left menu.

2
Review Identities

Under the 'Identities & Trusted Certificates' section, click the 'More' button to view your currently installed digital IDs.

3
Obtain a compatible certificate

Visit the Adobe Approved Trust List (AATL) webpage via Adobe's official documentation to find a certified provider and acquire a compatible digital ID.

REAL ID Limitations: While a REAL ID is valid for physical identification, secure document signing requires a cryptographic PFX/P12 file, a USB token, or a compatible smart card issued by an IT department or Certificate Authority.
