How to Change the Password for an Acrobat Digital Signature
Question details
The user needs to change the password associated with their digital signature ID when signing a PDF form.
- Product
- Adobe Acrobat / PDF
- Device & OS
- not provided
- Scenario
- Signing an official PDF document (e.g., an IRS form) that contains a digital signature field.
- Observed behavior
- A password prompt appears when clicking the digital signature field, and the user wants to update or change the password that protects their digital ID.
Verify whether your digital ID was created locally within your PDF software or issued by a third-party certificate provider, as externally managed credentials cannot be changed through the PDF reader directly.
Change the Digital ID Password in Acrobat Settings
Update the password for a self-signed digital ID directly through Acrobat's security preferences, provided it was created locally.
The password prompt you see is designed to protect your digital ID, not the PDF form itself. If you created a self-signed digital ID (a PKCS#12 file) directly in Acrobat, you can manage it from the application preferences.
Open Adobe Acrobat, go to the 'Edit' menu (Windows) or 'Acrobat' menu (Mac), and select 'Preferences'.
In the left-hand Categories pane, click on 'Signatures'.
Under the 'Identities & Trusted Certificates' section, click the 'More...' button.
Click on 'Digital IDs' on the left, select your specific digital ID file from the list, and choose the option to change the password if it is available. Note: If you have forgotten the password for a locally stored digital ID, Acrobat cannot recover it; you will need to delete the old ID and create a new one.
Contact Your Third-Party Certificate Provider
Manage passwords for digital IDs stored on smart cards or issued by external providers.

Frequently Asked Questions
What happens if I forget my digital signature password in Acrobat?
If you forget the password for a self-signed digital ID created in Acrobat, it cannot be recovered or reset. You will need to delete the existing ID from your preferences and create a completely new digital ID to sign future documents.
Why does my IRS form ask for a password when I click the signature field?
The password prompt is triggered by your digital ID software, which is required to cryptographically sign the document and verify your identity. The prompt comes from the security settings of your digital certificate, not from the IRS PDF form itself.
Can I remove a password requirement from a digital signature completely?
For security and non-repudiation reasons, standard digital IDs (especially those using PKCS#12 files) require a password. This ensures that only you can apply your cryptographic signature to a document, preventing unauthorized use.
