You've been there. A friend comes over with their new Android phone, and within the first five minutes, they ask the question, "Hey, what's the Wi-Fi password?" Rather than having to tell them the password is "IAmAParasite" (which is the best guest password ever, by the way), wouldn't it be easier just to hold up your phone and let your friend scan a QR code? Google agrees, which is why QR sharing is baked into Android 12.
There are three ways to share Wi-Fi credentials in Android 12. You can let them scan a QR code, or you can use Nearby Share. During the process, the Wi-Fi credentials will be shown in cleartext, so you can allow your friend to enter the Wi-Fi credentials that way too. The process to get to the QR code, cleartext, and Nearby Share are all located in basically the same place, so there's just one set of steps to find each below.
How to share Wi-Fi credentials on Android 12
- Swipe down your notification shade.
- Tap the arrow pointing to the right for Internet.
- Tap the Gear icon next to the Wi-Fi connection you're connected to. Note: If you want to share a different Wi-Fi connection, you need to connect to it first.
- In the connection settings, tap Share.
- Scan your fingerprint (or face) to verify it's you.
- You'll be presented with a QR code. Also on the screen are the SSID and the Wi-Fi password in cleartext. Your friend can scan the QR code or enter the Wi-Fi credentials manually.
- Optionally, tap Nearby Share to transfer the credentials using that protocol.
- Your recipient can then accept the credentials on their phone, which will automatically connect them to the Wi-Fi.
Pro-tip: If you have a lot of people coming over and using the Wi-Fi often, you can print out that QR code and post it on the wall for guests to scan on their own. Otherwise, using the QR code and/or cleartext will work for anyone, whether they're running Android or iOS. Nearby Share is, of course, limited to Android users.

I learnt a neat trick Samsung does with their phones. Earlier this summer on vacation I brought two different Samsung devices. I only have one SIM so only one had internet at any time but they're both logged on with the same Samsung account. At one time I had both powered on to transfer my covid cert to the other phone and the phone with the sim automagically enabled wifi sharing for the SIM-less phone and it logged on and got internet...
That's pretty neat, I think, as I had never connected the SIM-less phone to the other phone's shared internet before that.
