First off they're a great thing, when used appropriately.
Dropping 3k on a holiday, payment authorisation required, fair enough.
Buying from a website you've never used before, absolutely.
But I have to authorise my payment on my app every damn time I top up my gas or electric, I do this 3 to 4 times a week and always the same amount.
Tesco every week for the same day.
Topping up my child's lunch money account.
£5 on the lottery.
Surely there should be some kind of tracking that shows I regularly use these sites and they are 'safe' unless I suddenly try to do a £600 tesco?!
