Why Adobe Sign Recipients Are Not Asked for a PDF Password
Question details
The user needs to understand why a recipient is not prompted to enter a password before viewing and signing an Adobe Sign document.

- Product
- Device & OS
- not provided
- Scenario
- Sending a secure PDF agreement requiring a signature and expecting the recipient to authenticate with a password before accessing it.
- Observed behavior
- The recipient is able to open and sign the document without being prompted for the standard PDF document-open or permissions password.
Verify whether your goal is to protect the final signed document from unauthorized viewing or to authenticate the identity of the signer before they can access the agreement.
Configure a Signer Authentication Password in Agreement Settings
Set up a specific authentication password to require recipients to verify their identity before they can open and sign the document.
A standard PDF document-open or permissions password typically applies only after the signed PDF is finalized and returned. To protect the document during the active signing process, you must configure the signer authentication settings natively within the signing platform.
Log in to your Adobe Sign account and initiate a new agreement by clicking 'Send' or 'Request e-signatures'.
Enter the recipient's email address in the designated field within the 'Recipients' section.
Click the authentication dropdown menu (which usually defaults to 'Email') located next to the recipient's email address.
Choose 'Password' from the list of authentication options.
Enter a secure password, confirm it, and complete the rest of the agreement details before sending. The recipient will now be forced to enter this password to view and sign.

Frequently Asked Questions
Why does my PDF only ask for a password after it has been signed?
Standard PDF security settings, like document-open passwords, are often applied to the final compiled document. During the cloud signing process, the e-signature platform manages access, and the final encrypted file is generated only once all parties have completed signing.
Can I remove a password from a signed PDF?
Generally, signed PDFs are cryptographically locked to prevent tampering and preserve the integrity of the signatures. Removing the password or attempting to edit the document will usually invalidate the digital signature.
What happens if the recipient forgets the signer authentication password?
If the recipient loses or forgets the password required to open the agreement, the sender will typically need to cancel the current agreement and send a new one, or update the authentication method in the agreement's manage settings.
