Step 1Locate Wi-Fi Settings
Currently, there is only one flavor of Android 10, and that’s the “Stock Android” version directly from Google. However, in the near future, manufacturers like Samsung will put their own spin on Android 10 by applying an OEM skin such as One UI, which means the settings menus could be a little different on your phone.
So first, search your phone’s Settings menu for the “Wi-Fi” submenu. On Stock Android, that’s located in Settings –> Network & internet. Once you’ve found the Wi-Fi settings menu, go ahead and select it.
View Wi-Fi Passwords
One inside the Wi-Fi settings page, scroll past the list of available networks and select the “Saved networks” option. From there, you’ll see a list of all the Wi-Fi networks your phone remembers. Select one.
Now, choose the “Share” option towards the top of the screen. You’ll be asked to scan your fingerprint or face or enter your PIN or password. Upon doing so, you’ll see a QR code with that represents the network’s SSID and password. You could scan this with another device using a QR scanner if you wanted, but the password is also listed in plain text beneath the QR code, so you can copy it from there.
