What feature enables businesses to enforce secure user logins in DocuSign?

The feature that enables businesses to enforce secure user logins in DocuSign is Identity Provider Authentication. This approach utilizes an organization's existing identity management system to authenticate users, which enhances security by ensuring that only authorized individuals can access DocuSign. By integrating with identity providers, businesses can leverage their authentication mechanisms, such as single sign-on (SSO) capabilities, which provide a more seamless and secure way to manage user logins across various platforms. This method not only improves security but also simplifies the login process for users.

In contrast, Suggested Passwords are beneficial for encouraging strong password creation but do not directly enforce login security. Email Verification Codes add a layer of security through one-time codes sent to users' email accounts, but they are often used in conjunction with other authentication methods rather than as a primary login enforcement feature. Two-Factor Authentication does strengthen security by requiring an additional verification step beyond just a password, however, it is typically employed as a supplementary measure rather than a standalone method for enforcing secure logins compared to Identity Provider Authentication.
