# Link protection

Three ways to control access to a link, all Pro and up, all set from the
link's create dialog or edit page.

## Password protection

Visitors see a clean password page and must enter the correct password before
being redirected. Passwords are stored hashed — we can't read them either.
Unlocking lasts one hour per visitor.

## Expiration

Set a date and time after which the link stops redirecting. Optionally set a
**fallback URL** — expired visitors go there instead of seeing the branded
"link expired" page. You're notified when a link expires, and you can revive
one by clearing or extending its date.

## Click limits

Cap the total number of redirects. The count is enforced atomically — the
limit is exact even under heavy concurrent traffic. When it's reached the
link disables itself (or sends visitors to the fallback URL), and you're
notified at 80% and at the cap.

:::note
All three combine freely: a password-protected link can also expire and
carry a click limit.
