In Ziflow, each proof notification email contains a private proof URL for the recipient. 

That URL includes:

• Access to the specific proof

• The private URL link includes a secure digital key (access token) assigned to the reviewer it was sent to. This token is the reviewer's identity. Ziflow identifies the person who uses the private URL link as the intended reviewer for this specific proof.

Private proof URLs are intended to:

• Reduce login friction

• Allow fast access from email

• Support external or occasional reviewers

• Enable collaboration without requiring accounts for every participant

This approach prioritizes convenience, but it relies on correct link handling to avoid confusion.

What this means

When someone clicks a private proof URL, Ziflow assumes they are the original recipient and opens the proof in that reviewer’s name.

No additional sign-in is required unless you configure proof security to require reviewers to sign into Ziflow. 

Do not share your private proof URL

To avoid sharing your proof link unintentionally:

• Do not forward your proof notification email to someone else

• Do not copy and share your private proof URL link with someone else

Example: David is sent a proof notification email and forwards it to Lisa.

If Lisa opens a proof using David's link:

• Within that proof, Lisa is treated as David

• All comments and decisions are attributed to David

Lisa does not gain access to David's account or account settings. Lisa can only see your proof review.

Best practices for sharing proofs

To ensure comments and decisions are attributed correctly:

• Do not forward proof notification emails: Forwarding a proof email shares your personal access link.
• Add reviewers directly to the proof: Each reviewer receives their own notification email and access link. See Add / remove reviewers or edit reviewer settings in a proof review.
• Use the public URL when appropriate: Depending on configuration, a Public URL can be used. See Share a proof / Add reviewers.
• Enable additional security settings if needed: You can require authentication or restrict link sharing to improve traceability and security. See Configure proof security when creating a proof.

What to do if you use someone's link by mistake

If you accessed a proof using the wrong link:

1. Clear your browser cache and cookies.

2. Reopen the proof using either:

   • Your own notification email

   • The public URL (if applicable)

This ensures you are identified correctly going forward. You will have to redo your comments in your own review.
