Email authentication in Dropbox DocSend

You can require visitors to verify their email addresses before gaining access to your shared content, providing you with even greater security and control of who views your content. When enabled, this feature sends an email to the visitor so that they can verify that they are who they claim to be.

Visitor Experience

Visitors will be prompted to check their email for a verification link to access your shared content. Upon clicking Verify email address, they'll be redirected to your content. 

The verification link will remain valid for up to one hour. Attempting to verify an email address after the link has expired will result in an error message, and the visitor will have to re-enter their email address to get a new verification email.

In-app experience

Visitors who have been verified will have a verification badge as part of their contact information. The badge will be visible on the document details page, the visit notification emails, the Accounts tab, and Dashboard.

If a visitor is already verified, the badge will appear next to their name on other visits, even if another link they accessed does not require email verification.
