I've had my P3 setup for several years now with gmail notifications sent to me for any alerts.
Recently the alerts have failed due to something google has done as i receive a message stating "Someone just used your password to try to sign in to your account from a non-Google app. Google blocked them, but you should check what happened"

When i click to check google tells me "Google blocked the app you were trying to use because it doesn't meet our security standards."

Anybody know what i need to change to get this to work again?
