				**Warning** This feature has options which are not backwards compatible, disabling

				it may have unintended consequences.

				## Log in with QR (`feature_login_with_qr`)

				Enables logging in to Element Web/Desktop by using Element X to scan a QR code.

				Requires server support, based on the v2024 edition of [MSC4108](https://github.com/matrix-org/matrix-spec-proposals/pull/4108).

				Can only be configured via config.json, as labs flags cannot be set until after login, and are cleared on log out. The UI option is disabled.

				Note, this does not affect the existing `Link new device` flow using the same MSC.
