Adobe Acrobat error during signing documents

[Ing. Oto Voženílek]

Adobe Acrobat error
We use Adobe Sign to approve important documents. Each signer has created an Adobe account, created the necessary signatures and settings.
When a document is included in the signing round, notifications are sequentially generated to each participant about the need for their interaction during the e-signing process. The notifications arrive via email and include a "Check and Sign" link to an authorized page where the user simply clicks on the necessary fields and the signatures are automatically applied. There is no need on his part to authenticate during this process.
The problem arises when one of the signers FORWARDS his email with the link to someone else. If the next recipient clicks on the "Check and Sign" link, they are taken to the same page as the notified user and are able to sign the document with the signature of the originally notified person!
The subsequent signature notification comes on behalf of the original user who was prompted to sign the document. Even from the signature audit it is not obvious that an unauthorized signature has occurred.
This situation occurs if no additional authentication method is chosen for signing (password, email+password), only email authentication.

Hi Ing. Oto Voženílek,

Thank you for reaching out.

As mentioned above, the email is forwarded. Could you please share the reason why the email was forwarded?

Please share the screen recording of the workflow to better understand the issue. You may create a test document and send it similarly. Also, Share the audit report for that document. We will get this behavior checked with the team. 

Let us know if you need any help.

Thanks,

Meenakshi

Hello,
The email notification is forwarded by the user out of ignorance, and due to not understanding the consequences of what their actions are causing. He forwards it even though he is warned in the message not to forward it.
Our question is whether it is possible to set somewhere that when clicking on a link in an email, the user is prompted in the web browser to authenticate with the password of their Adobe account? Alternatively, does Adobe foresee such an option in the future?
