The third Android Q beta was launched yesterday for a host of Pixel and non-Pixel devices. The beta brings many changes and one of the most prominent ones makes it a lot easier to access Wi-Fi passwords stored on your device. Until now, one had to rely on third-party apps (or ROMs) to share WiFi passwords via a QR Code. Sharing it via plaintext was not possible either.

In Android Q, Google is changing that. When you tap on the settings for any Wi-Fi network you are currently connected to or have ever been connected to, there’s a sharing option. This requires your device’s PIN or a fingerprint to access, but once you have, you’ll see a QR code for automatically connecting to that network as well as the Wi-Fi password itself in plain text.
