What is the easy way to connect other smartphones to the Wi-Fi you are currently using?-Why can't I ask about Android now?

You are currently connected to Wi-Fi and want to connect another smartphone to it? I want to make it easier for other people because I am enough to enter the password I set.

First, make sure you're connected to the Wi-Fi you want to share. After that, open the Wi-Fi screen of the Settings app and look at the Wi-Fi access point you are currently connected to, and you should see a gear button on the right end (some devices may not have a gear but a "tap to share password" etc.). When you tap this, the information you need to connect to the Wi-Fi access point will be displayed as a QR code on the screen.

After that, just hold the camera of the other smartphone you want to connect to the same Wi-Fi over the QR code. Regardless of the type of smartphone, you can use it as long as you have a camera app that can read the QR code, so you don't have to worry about Android or iPhone.

In addition, the generated QR code has the Wi-Fi access point information embedded in the format "WIFI: T: security method; P: password; S: SSID name;". The password is written in plain text (unencrypted string) so that it can be read on any smartphone without a special application, so it should be handled carefully. Avoid saving the QR code as an image, such as taking a screenshot, and try to use it only on the spot.
