Click Verify identity to download and you are asked how you would like to confirm you are the named recipient.

The two options
| How it works | Good if | |
|---|---|---|
| ID Austria | Confirm with your government eID on your phone | You already hold ID Austria: it takes seconds |
| WebID | A quick video or AutoIdent check against your ID document | You do not. Have your passport or ID card to hand |
Your ID does not reach swipesign
The page says so directly: your verification is handled by the provider. Swipesign never sees your ID document.
The provider runs the check and reports the result. Images of your passport, the video, the document scan: all stay with them. See What swipesign can and cannot see of your ID.
You only do it once
When the check passes you get a personal access code. Keep it: you can come back to this transfer later and use the code instead of verifying again. See Using your access code.
What the sender sees
Three things, in order: that you opened the link, that you passed the check, and that you downloaded the files. Each is timestamped in their audit trail.
