Protect a share with watermarks and passphrases

Intermediate4 min readUpdated May 2026

When you share work outside the team, you decide how protected the link is. Curtyn gives you passphrases, watermarks, expiry dates and per-recipient links. This guide covers locking a share down.

Before you start

You'll need a share already set up. See “Share a project with a client” first.

1

Open the share's protection settings

In the share controls, find the protection options. They sit alongside the share itself, so you tighten a link without rebuilding it.

2

Add a passphrase

Set a passphrase so the link only opens for someone who has it. Send the passphrase separately from the link, and a forwarded message no longer hands over access on its own.

3

Turn on a watermark

A watermark lays identifying text over the work, so a screen grab can be traced back. It is the deterrent for work that is sensitive before release.

Watermark and downloads

A watermarked share turns downloads off. The viewer can watch the work in the browser, but they can't take an unmarked copy away.

4

Set an expiry date

Give the link an end date so access closes on its own. A review link that expires after the job is a link you don't have to remember to revoke.

5

Use per-recipient links

Instead of one link for everyone, issue a separate link per person. You can see who has opened what, and switch off one person's access without disturbing anyone else's.
