How can access to envelopes be restricted for recipients on a domain?

To restrict access to envelopes for recipients on a specific domain, selecting the option that requires a login when opening envelopes is an effective measure. By choosing to always require login, you ensure that only authenticated users can access the documents contained within the envelope. This adds a layer of security, ensuring that only intended recipients who have logged in can view or interact with the contents of the envelope.

Requiring login is particularly useful for maintaining confidentiality and protecting sensitive information, as it mitigates the risk of unauthorized access. Only users with valid credentials will be able to access the envelope, which can help prevent fraudulent activities or accidental leakage of information.

Establishing IP address restrictions, while beneficial for controlling access based on the network from which recipients can open envelopes, does not specifically require recipients to log in and can still allow access to unauthorized users if they are on an approved IP address. The focus on requiring a secure authentication process directly addresses the need for controlled access, which the login requirement option specifically provides.
