Solution 1Recommended

Update Adobe Account Identity and Certificate Settings

Sign out of your current account and configure the correct identity settings for both account services and digital certificates to ensure signatures display the proper name.

Digital signatures rely on secure certificates that are distinct from your standard application login. To fully update your identity, you must sign into the correct Adobe account and update your digital ID settings.

1
Sign out of the current account

Open Adobe Acrobat, click on your profile icon or name at the top right of the application window, and select 'Sign Out'.

2
Sign in with the new identity

Restart Acrobat and sign back in using the correct Adobe ID credentials associated with the identity you want to use for online reviews.

3
Access signature preferences

Navigate to the top menu bar, click on 'Acrobat' (or 'Edit' on Windows), select 'Preferences', and choose 'Signatures' from the left sidebar.

4
Update digital ID settings

Under 'Identities & Trusted Certificates', click the 'More' button. Select 'Digital IDs', find your current certificate, and either edit its properties or add a new digital ID with the correct identity information.

Separate Management: Changing your login account will update your identity for online reviews and services, but it will not automatically change the author name displayed on standard offline PDF comments.

Frequently Asked Questions

Does changing my comment name also update my digital signature identity?

No, comment author names and digital signature identities are managed entirely separately. You must update your digital certificate or Digital ID settings in preferences to change the name associated with your signatures.

Why is my login name always used for PDF comments?

Acrobat has a default setting enabled called 'Always use Log-in Name for Author name.' By unchecking this box in your Commenting Preferences, you can manually input and set a custom author name for your annotations.

Will changing my digital identity affect PDFs I have already signed?

No. Documents that have already been digitally signed will retain the identity, certificate information, and timestamp that were valid at the exact moment the signature was originally applied.
