Create a Self-Signed Certificate in the Windows Store
Generating a new self-signed certificate and storing it in the Windows Certificate Store often prevents the email from displaying on the visible signature.
When you create a self-signed digital ID, the setup wizard may ask for an email address. However, by saving this certificate directly to the Windows Certificate Store rather than a local file, the email address is generally omitted from the visible signature block on the document.
Open your PDF document in your PDF editor and navigate to the Protect or Digital Signature tool.
Click to sign the document and choose the option to create a new digital ID or self-signed certificate.
When prompted by the wizard, enter your name and organizational details. You can leave the email address blank if the software permits, or fill it out as required.
Select the option to save the new digital ID to the 'Windows Certificate Store' instead of saving it as a standalone digital ID file.
Apply the new signature to your document and verify that the email address is hidden in the visible signature block.

Frequently Asked Questions
Can I edit an existing digital certificate to remove my email address?
Generally, digital certificates cannot be edited once they are created, as this would compromise their security and cryptographic integrity. You will need to generate a completely new digital ID without the email address.
Why does my enterprise digital signature still display my email?
Enterprise digital signatures are often linked to a corporate time-stamp server or Active Directory that automatically fetches and embeds your contact information. You must consult your IT department to modify these centralized configurations.
Is an email address strictly required for a valid digital signature?
No, an email address is not strictly required for a digital signature to be cryptographically valid. However, some certificate creation wizards may prompt you for one to complete the initial setup process.
