How to Reset or Replace a Lost Acrobat Digital ID Signature Password
Question details
The user is unable to sign a document because they have forgotten their Digital ID signature password and wants to know if it can be reset or recovered.
- Product
- Adobe Acrobat 9 Standard
- Device & OS
- not provided
- Scenario
- Attempting to digitally sign a PDF document but being blocked by a password prompt for an unknown or forgotten Digital ID password.
- Observed behavior
- The application requests the original Digital ID password to complete the document signing process, preventing the user from signing the file without it.
Before proceeding, check if you have a secondary backup of your digital ID file (.pfx or .p12) saved elsewhere or if your IT department manages your certificates, as local digital ID passwords cannot be extracted once lost.
Create a New Digital ID to Replace the Forgotten One
Because Digital ID passwords are encrypted and intentionally unrecoverable by design, the only valid solution is to generate a completely new Digital ID for future signing.
Adobe Acrobat does not store your digital ID password anywhere on the system, meaning there is no 'Forgot Password' recovery mechanism. To resume signing documents, you must abandon the locked ID and create a fresh digital signature profile.
Open your PDF application and navigate to the security or signature settings. In older versions like Acrobat 9, go to 'Advanced' > 'Security Settings'. In newer versions, go to 'Edit' > 'Preferences' and select 'Signatures'.
Select 'Digital IDs' from the left pane or menu, then click the 'Add ID' button (often represented by a plus icon) to initiate the creation of a new profile.
Choose the option 'A new digital ID I want to create now'. Proceed to fill in your identity details, including your Name, Organizational Unit, Organization Name, and Email Address.
Choose a secure but memorable password for this new Digital ID. Select a location on your computer to save the new .pfx or .p12 file, and click 'Finish'.
Return to your document, click the signature field, and select your newly created Digital ID from the drop-down menu to sign the PDF.

Frequently Asked Questions
Can customer support recover my forgotten Digital ID password?
No, software providers do not store your Digital ID passwords. For security reasons, the password is only known to the creator of the ID, and lost passwords cannot be retrieved by customer support.
Will creating a new Digital ID invalidate my previously signed documents?
No, documents that were already signed with your old Digital ID will remain perfectly valid. You will simply need to use your newly created Digital ID for all future document signatures.
Where is my Digital ID file saved on my computer?
By default, Windows typically stores the .pfx or .p12 Digital ID files in a hidden application data folder, but you can choose to save newly created IDs in any accessible folder, such as your Documents or Desktop, during the setup process.
