It looks like Steam is getting a QR code login option

The latest update of the Steam code includes signs of a new login method coming soon: scan the QR code using the Steam mobile app.That is based on A tweet Written by Pavel Djundik, the creator of SteamDB.

This feature has not yet been launched, but it seems that it may be released with the Steam platform later this year to make it easier to log in to the handheld computer. Deck’s touch screen should mean that no password will be entered and also It’s cumbersome, but logging in by scanning the QR code does sound better to me.
