One-time QR codes for VPN client pairing

The website creates short-lived pairing codes for supported clients instead of displaying a permanent or reusable subscription address.

Short-lived and single-use

Each QR code is intended for one device-pairing attempt and expires after five minutes. Using the code once, waiting until it expires or attempting to reuse an old screenshot requires a new code.

Validity: Five minutes from creation.
Usage: One successful claim only.
Browser behavior: Information only; no configuration is returned.
Caching: Pairing responses are marked not to be stored.

Why the code is not a subscription link

A reusable subscription address can remain useful long after it is copied. A pairing code has a narrower purpose: it lets a supported client request configuration through a protected, time-limited flow. The public website does not place the underlying configuration in the QR code.
