Question details
The user is prompted for a password when attempting to sign a PDF document and wants to know how to change or remove this password requirement.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Signing a PDF document using a digital ID.
- Observed behavior
- A password prompt appears in the Sign Document dialog. The user wishes to update the existing password or remove the password requirement entirely, noting that colleagues are able to sign documents without entering one.
Verify whether your organization's security policies require a password-protected digital ID for signatures before attempting to bypass it. Be prepared to create a new digital ID if you cannot remember your current password.
Create a New Digital ID Stored in the Windows Certificate Store
Since an existing digital ID password generally cannot be removed or bypassed, the best approach is to create a new digital ID that uses your Windows login instead of a separate password.
Digital IDs in Acrobat use underlying security mechanisms (often PKCS#12 files) that are inherently password-protected. To stop entering a password every time you sign, you can generate a new self-signed digital ID stored directly in the Windows Certificate Store. This method uses your active Windows session for authentication.
In Adobe Acrobat, go to Edit > Preferences (or Acrobat > Settings on Mac).
Select 'Signatures' from the categories list on the left side, then click the 'More' button under the 'Identities & Trusted Certificates' section.
Click 'Digital IDs' on the left menu, then click the 'Add ID' button (a plus icon) at the top of the window.
Choose 'A new digital ID I want to create now' and click Next.
Select 'Windows Certificate Store' (this is what prevents Acrobat from prompting for a separate password every time you sign) and click Next. Fill in your identity details, such as name and email, and click Finish.

Frequently Asked Questions
Can I recover my forgotten digital ID password in Acrobat?
No, for security reasons, Adobe Acrobat does not provide a way to recover a forgotten digital ID password. If you lose it, you will need to create a new digital ID to sign future documents.
Why do my colleagues not need a password to sign PDFs?
Your colleagues likely have their digital IDs stored in the Windows Certificate Store or macOS Keychain. These storage methods use their computer login for authentication instead of prompting for a separate password during signing.
How do I delete an old password-protected digital ID from Acrobat?
To remove an old digital ID, go to Edit > Preferences > Signatures > Identities & Trusted Certificates. Select the old ID from the list and click 'Remove ID'. If it is a file-based ID, you may also need to delete the underlying .pfx or .p12 file from your computer's hard drive.
