Share Wi-Fi for a day, or write it to an NFC tag

Share for a day on a Wi-Fi network makes a one-time link that opens once within 24 hours, shown as a QR code. Your item stays yours, and you can cancel the link under Sharing.

On Android, Write to NFC tag puts a network on a tag so guests with an Android phone tap and confirm to join. A tag isn’t encrypted, so the app says that first. iPhones don’t join from tags, and WEP, WPA3-only and Enterprise networks can’t go on one. See Wi-Fi networks.
