Your link or QR code
What it is, and why there is no password.
It takes you to the couple's own wedding website, where you can say whether you are coming. It is theirs, not ours — their names, their design, their words.
You do not need an account or a password, and there is nothing to download. Open it and you are in.
If the code will not scan
Open your phone's camera and hold it steady over the square, about a hand's width away, in decent light. Most phones show a link to tap within a second or two.
If nothing happens, the couple can send you the same thing as an ordinary link by email or message — it does exactly the same job.
The link says it does not recognise me
Check you have the whole address — links sent by message are often cut in half, and the part after the last slash is the bit that matters.
If it is complete and still refuses, ask the couple to send it again. They can see which link belongs to your household and we cannot.
