- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Creating and applying a new certificate-based digital ID for signing PDF documents securely.
- Observed behavior
- The user needs the digital signature to prompt for a password before being applied, while automatically recording the accurate signing date and time.
Before configuring a new digital ID, ensure your Adobe Acrobat software is fully up to date by navigating to Help > Check for Updates and restarting your computer if necessary.
Create a Password-Protected Self-Signed Digital ID
Set up a new certificate-based digital ID saved as a file, which allows you to establish a mandatory password for applying signatures.
Certificate-based digital signatures are structurally different from simple drawn or typed signatures. By creating a self-signed digital ID stored as a file on your computer, you can enforce password protection to ensure only you can sign documents.
Open Adobe Acrobat, navigate to the 'Edit' menu, and select 'Preferences'. In the left-hand panel, click on the 'Signatures' category.
Locate the 'Identities & Trusted Certificates' section and click the 'More' button to open the Digital ID settings window.
Highlight 'Digital IDs' in the left pane, click the 'Add ID' button at the top, and select 'A new digital ID I want to create now'. Click 'Next'.
Select 'New PKCS#12 digital ID file' (which saves the ID to your computer) and click 'Next'. Fill in your identity details such as Name, Organization, and Email.
Choose a file location to save the digital ID. In the password fields, enter a strong password and confirm it. Click 'Finish'. Whenever you use this digital ID to sign a PDF, Acrobat will prompt you for this password and automatically append the correct date and time.

Frequently Asked Questions
Why is my Adobe Acrobat digital signature not asking for a password?
If your digital ID was stored in the Windows Certificate Store rather than as an independent file, it uses your Windows login credentials for security and bypasses the password prompt in Acrobat. To require a password, create a new self-signed digital ID and save it as a PKCS#12 file (.pfx or .p12).
Does a digital signature automatically include the date and time?
Yes. When you sign a document using a certificate-based digital signature in Acrobat or standard PDF editors, the software automatically records the precise date and time the signature is applied based on your system clock or a secure time stamp server.
What is the difference between an electronic signature and a digital signature?
An electronic signature can be a simple drawn image or typed name used to indicate intent. A digital signature uses certificate-based cryptography (Digital IDs) to verify the signer's identity and detect if the document was altered after signing.
