The Guest Wi‑Fi Handshake: Get Someone Online Without Texting the Password
Here’s the scene: you’re at a rental, a friend’s place or a coffee shop that wrote the Wi‑Fi key on a whiteboard that’s since been erased. Your phone joined hours ago. Now your laptop needs it to push a build, a friend needs it to stop burning hotspot data, and somebody in the group chat types “what’s the wifi??” for the third time.
The lazy move is to dig up the password and paste it into the chat. Don’t. That message lives forever, gets backed up to three clouds and ends up on phones you’ll never see again. Your phone already knows the password and Android has a built‑in handshake for this: a QR code, guarded by your fingerprint, face or PIN.
My rule: QR first, read the password out loud second, text it never. This page shows both moves on Pixel and Samsung, plus the times you shouldn’t do either.
What You Need
- An Android phone running Android 10 or newer.
- Your phone must have joined the network before, so the password is already saved on it.
- Your own screen lock (fingerprint, face or PIN). Android asks for it before it shows anything. That gate is the whole point.
- No apps required. Skip the “Wi‑Fi password viewer” apps in the Play Store. Most want root or permissions they have no business asking for.
Pixel and Most Stock Android Phones
Menu names shift a little between Android versions and phone makers, but the shape is the same.
-
Step 1: Open Settings
Open the Settings app. On your own phone, not the one you’re trying to get online.
-
Step 2: Go to Internet
Tap Network & internet, then Internet. On older Android 10 or 11 builds this one is labelled Wi‑Fi.
-
Step 3: Open the network’s settings
Find the network you’re connected to and tap the gear icon next to its name.
-
Step 4: Tap Share
Tap Share. This is the handshake button. Nothing has been revealed yet.
-
Step 5: Confirm it’s you
Confirm with your fingerprint, face or PIN. If someone else could unlock your phone, they could do this too, so it’s worth having a real screen lock.
-
Step 6: Let them scan, or read it
A QR code appears with the password as text under the code. Turn the screen around and let your friend’s camera scan it. For a laptop that can’t scan, read the password out or type it in yourself, then back out of the screen.
Samsung Galaxy
-
Step 1: Open Wi‑Fi settings
Go to Settings > Connections > Wi‑Fi.
-
Step 2: Open the network’s settings
Tap the gear icon next to the network you’re on.
-
Step 3: Show the QR code
Tap QR code at the bottom of the screen. For a friend’s phone, you’re done: let them scan it.
-
Step 4: Need the actual text?
Samsung doesn’t print the password under the code. Tap Save as image, then scan that saved image with your phone’s built‑in camera or scanner to read the password. Then delete the image so a plain‑text Wi‑Fi key isn’t sitting in your gallery and cloud backup.
When Not to Flash the Password
- It isn’t your network to hand out. Work Wi‑Fi, a client’s office, the host’s private network. If someone gave you access, it’s not yours to re‑gift. Point your friend at the guest network or the person who runs it.
- You’re on a borrowed phone. Don’t pull up a password on someone else’s device, and never hit Save as image there. That PNG lands in their gallery and syncs to their cloud backup.
- It’s the kid’s tablet. If the home network has parental filtering, the kid now knows the key and can put any device on it. Scan the QR yourself and hand the tablet back.
- Workplace BYOD phones. If your phone is enrolled in a work profile, the work network’s settings belong to IT. Sharing them can be a policy violation, and it’s often blocked anyway.
- The network looks right but your phone “forgot” it. A café network with the same name but no saved password can be an evil‑twin hotspot. Don’t take the “correct” password from a stranger’s phone. Ask staff.
Once you’re online on someone else’s network, setting up Private DNS stops that router from reading every lookup you make. If you’re handing your own phone’s hotspot around instead, turn on Data Saver before your friend’s phone starts downloading every app update at once.
