Create a New Digital ID in Adobe Acrobat

Generate a fresh digital certificate to restore your ability to sign documents if your previous ID file was not transferred successfully.

Digital IDs are often stored locally on your device rather than in the cloud. During a standard data transfer, the specific certificate files (.pfx or .p12) containing your Digital ID might be left behind. Creating a new Digital ID is the fastest way to resume signing PDF documents securely.

1
Access Preferences

Open Adobe Acrobat, click on the 'Edit' menu at the top, and select 'Preferences'.

2
Navigate to Trusted Certificates

In the left panel, choose 'Signatures'. On the right side, find the 'Identities & Trusted Certificates' section and click the 'More' button.

3
Add a New ID

Select 'Digital IDs' from the tree view on the left, then click the 'Add ID' icon at the top of the window. Choose the option 'A new digital ID I want to create now'.

4
Configure ID Details

Follow the on-screen prompts to enter your name, organizational unit, and email address. Finally, set a secure password to protect your new Digital ID and click 'Finish'.

Frequently Asked Questions

Why did my Digital ID disappear after replacing my laptop?

Digital IDs are usually stored locally on your device's hard drive. If the specific certificate files were not manually exported and copied over to the new laptop during the data transfer process, Acrobat will not recognize your previous signatures.

How can I transfer an existing Digital ID to a new computer?

You need to export your Digital ID from Acrobat on your old computer as a .pfx or .p12 file, transfer that file to the new computer using a USB drive or secure cloud storage, and then import it utilizing Acrobat's 'Identities & Trusted Certificates' menu.

Will creating a new Digital ID affect the PDFs I previously signed?

No. Documents you previously signed are locked with that specific timestamp and signature instance, so they will remain valid and intact. You will simply use the newly created Digital ID for signing any future documents.
