WireGuard with Android

Download and install WireGuard from Play Store

Log in this site.
Enter Config Generator
Click on your favorite option.
Click on "Generate".
Download or extract files.

Launch WireGuard. Click the + button, choose "Scan from QR code", and choose a name

Alternatively, download .conf file and use "Import from file or archive" (in this case, the config file name will be used as interface name, but our Config Generator builds too complex names. So, rename the .conf file you want to use to a friendly interface name)

When OS prompts a security warning, click "Allow"

Switch to activate
