Question details
The user needs to set up and manage digital IDs for certificate-based signatures in Adobe Acrobat, which involves creating new IDs, customizing appearances, enforcing password protection, and removing obsolete IDs.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Setting up, modifying, or removing secure digital signatures for PDF document authentication.
- Observed behavior
- Requires step-by-step navigation through Acrobat's signature settings to generate, protect, and safely delete digital IDs.
Ensure you have any existing certificate files ready if you plan to import an ID, and prepare a strong, unique password to secure your newly created digital signature.
Create or Import a Digital ID
Use Acrobat's signature preferences to generate a new certificate-based digital ID or import an existing one for document signing.
A digital ID contains a private key for signing and a public key (certificate) for validation. Creating a self-signed digital ID is suitable for internal organizational use, while importing a third-party certificate provides higher security validation.
Go to 'Edit' > 'Preferences' (Windows) or 'Acrobat' > 'Preferences' (Mac), and select 'Signatures' from the categories on the left.
Under the 'Identities & Trusted Certificates' section, click the 'More' button.
Select 'Digital IDs' in the left pane, then click the 'Add ID' button located at the top.
Choose whether to create a new digital ID or import an existing file. Enter your identity information (name, email) and set a strong password to protect the private key.

Delete an Existing Digital ID
Remove a digital ID that is no longer needed or if the password has been lost, directly from the preferences menu.
Create and Apply Digital Signatures Easily with WPS PDF

- 3. Create Your Signature: Click on 'Sign Document' or 'Digital Signature', then choose to create a new signature by typing, drawing, or uploading an image.
- 4. Apply and Save: Place the signature securely on your document, apply any necessary file encryptions, and save your finalized PDF.

Frequently Asked Questions
What happens if I forget my digital ID password in Acrobat?
If you forget your digital ID password, the private key cannot be recovered due to strong encryption. You will need to delete the existing digital ID from your preferences and create a new one to continue signing documents.
Can I customize the appearance of my digital signature?
Yes. In the Acrobat Signature Preferences, you can configure the signature appearance by adding a scanned handwritten signature, a company logo, or changing the text information (such as date, location, and reason) that appears alongside the certificate.
Why is the 'Remove ID' button grayed out for my digital ID?
The 'Remove ID' button may be inactive if the digital ID is currently in use, stored in the Windows Certificate Store, or managed by your system administrator. In such cases, the ID must be removed via your operating system's certificate management tool rather than directly through Acrobat.
