Requests with options, and missing information

Some websites ask for one of several options or for optional information; you choose what is sent. If they ask for something your credential does not have, nothing is sent.

Steps

  1. Step 1: Look at the “Options” card on the approval screen

    Each group of options is labelled Required or Optional.

    Share approval: who is asking, the information that will be sent and the approve button.
    Share approval
  2. Step 2: If it is required, choose one

    “The verifier needs one of these. Choose what to share — only that is sent.”

  3. Step 3: If it is optional, decide

    You can finish without sharing it. Optional information is not sent unless you turn it on; if you do not want to, leave Don't share selected.

  4. Step 4: If something missing from your credential is requested, read the message

    The wallet never sends a credential with missing information; it tells you why (see the table below).

  5. Step 5: Get or refresh what is needed, then scan again

    Get the missing credential from the institution or refresh yours; then scan the QR code on the website again.

Good to know

  • Only the fields you choose and approve are sent; the rest stays on your phone.
  • Requested fields that are not in your credential are listed separately and are not sent.
