Password-protected short links: when they earn their keep
A password gate on a link is not encryption. Here is what it does protect, and how to use it without annoying people.

What it actually does
The short link serves a password form instead of redirecting. A correct password sets a short-lived cookie and the redirect proceeds. The destination URL is never shown until the password is right.
Good uses
Pre-launch pages you want to share with a handful of reviewers. Pricing documents sent to a specific prospect. Internal resources shared over channels you do not fully control. Beta downloads. Event materials for registered attendees.
What it does not protect against
Anyone who passes the gate has the real destination and can share it directly. If the destination itself is public, the password only slows down casual discovery. For genuinely sensitive material, protect the destination, not the doorway.
Link previews stop working — by design
Crawlers hitting a protected link see the password page, so Slack, WhatsApp and Facebook previews show the gate rather than your content. That is correct behaviour, and worth warning colleagues about before they think the link is broken.
Make the gate look like you
A generic password box makes people assume phishing. Custom colours, your logo and a line explaining what is behind the gate turn a suspicious page into an expected one. Adding a contact address for people who do not have the password prevents most support tickets.
Combine with expiry
A password plus an expiry date, or a click limit, is a much stronger control than either alone — and it means an old link stops working without you having to remember to delete it.
