How to Connect to Wifi Without Password on Android
What's the fastest way to share a Wi-Fi password with visiting friends and family? You could write it down and hand it to them on a piece of paper, but that's not very secure. And setting up a guest Wi-Fi network can be a hassle. Luckily, there are ways to quickly share these credentials without compromising your network. Here's how to do it from an iPhone, iPad, Mac, Android device, and Windows PC.

Apple makes this a seamless process, as long as you all have an iPhone, iPad, or Mac and have everything set up correctly. In order to share your Wi-Fi password, both devices should have Wi-Fi and Bluetooth turned on and be signed into iCloud with their respective Apple IDs. You each also need to have the email address of the other saved in Contacts.
Once all these requirements are met, bring the two devices within Bluetooth and Wi-Fi range and make sure the sharing device is unlocked and connected to the network. Have the device without internet select the network to be shared and a message should pop up on the sharing device's screen. Tap Share Password to give the other device access to the Wi-Fi network.
Android devices share Wi-Fi passwords through QR code generation, so Apple devices can receive login credentials this way as well. In order to share and receive a password, your Android device must be running Android 10 or later. Make sure you're connected to the network you wish to share, then open Settings > Connections > Wi-Fi, or your phone's equivalent.
The network that is selected should also have a gear icon next to the network name. Tap the gear, then select the QR code icon at the bottom of the screen. A unique QR code will be generated, which you can then save to your phone or share to a contact.
The network connection is shared when the other person opens their phone's camera and scans the QR code. All they need to do is tap the pop-up message on the screen to open their Wi-Fi settings and connect to the network.
Are you the one in need of internet? Most smartphones have built-in QR code scanners at this point, but you can also head to the Wi-Fi settings page. Here, you will find a tiny QR code icon at the top of the page that will allow you to scan codes once clicked.
QR Code Generator
For devices that cannot create a QR code or use Apple's Wi-Fi sharing method, use a free QR code generator to share the password. You can find plenty of tools with a quick Google search; just make sure it supports Wi-Fi information. For this demonstration, I am using QR Code Generator, but QiFi.org focuses specifically on Wi-Fi codes, while Qrafter has a free iOS app.

All you need to do is select the Wi-Fi setting (if there is more than one mode), then enter the SSID (network name) and password. You may also need to enter the security type, so check the Wi-Fi settings on your device if you don't already know it. Once all the information is entered, click Generate to produce the code.
At this point, the QR code can be used by any device with a built-in scanner or mobile app. Download the code as an image and send it to those in need or simply have them scan the code from the screen. QR Code Generator even allows you to embed the code or customize what the code looks like by changing its shape, adding color, or even inserting a logo. This makes it easy to print out and make available for guests.
Using a QR code generator is a great option for sharing Wi-Fi from iPhone to Android or to and from Windows PCs, since Microsoft has disabled network sharing with contacts in Wi-Fi Sense.
