Need to create a Digital ID?
What you need
- Adobe Acrobat or Adobe Acrobat Reader
- No external certificate authority is required (this is a self‑signed Digital ID)
Steps (Windows & Mac)
- Open Adobe Acrobat or Acrobat Reader
- Go to Menu / Edit → Preferences
- Select Signatures
- Under Identities & Trusted Certificates, click More
- Select Digital IDs
- Click the Add (+) icon
- Choose “A new digital ID I want to create now”, then click Next
- Choose where to store it:
- New PKCS#12 digital ID file (recommended)
- Enter your identity details:
- Name
- Organization (optional)
- Email address
- For Key Algorithm, select:
- 2048‑bit RSA (recommended by Adobe)
- Click Next
- Create and confirm a password for the Digital ID
- Click Finish
Your Adobe Digital ID is now created and ready to use
How you use it
- When you digitally sign a PDF, Adobe will prompt you to select this Digital ID.
- The signature is cryptographically bound to the document, showing if it’s been altered after signing.
Important notes (worth knowing)
- This type of Digital ID is self‑signed and ideal for:
- Internal documents
- Approvals
- Forms
- External recipients may see a notice that the signature is not from a trusted authority (this is normal).
- If you forget the password or lose the file, the Digital ID cannot be recovered—back it up securely
