How to Reset a Forgotten Password on an Acrobat Sign PDF
Question details
The user wants to know how to reset or change a forgotten password for a PDF document that was signed using Adobe Acrobat Sign.

- Product
- Adobe Acrobat Sign
- Device & OS
- not provided
- Scenario
- The user has lost or forgotten the password required to open a PDF completed via Acrobat Sign and needs to regain access.
- Observed behavior
- The PDF remains locked, and there is no native password reset option available within the Acrobat Sign interface for completed documents.
Verify that you are checking the correct email account for the original signing request, as senders sometimes include access instructions or secondary authentication details in the email body.
Contact the Document Sender for a New Copy
Because Acrobat Sign permanently encrypts signed documents with the set password, it cannot be reset by the recipient. You must request a new copy or a new signature request from the sender.
Adobe Acrobat Sign employs strict cryptographic security to ensure document integrity and legal compliance. Once a password is applied and the document is completed, the password is not stored in a recoverable format.
To regain access, the only reliable method is to reach out to the original sender or the organization that initiated the signing process.
Search your email inbox for the original 'Please sign' or 'Completed' email from Adobe Acrobat Sign to find the sender's email address.
Send an email to the document owner explaining that the password is lost and request an accessible copy of the completed PDF.
If the sender cannot provide an unlocked copy, ask them to generate and send a brand-new signing request to your email address.
