I order something online. Get asked to confirm the purchase on my bank app. Log in to my bank website from my laptop as I am already there, enter my password. Then I get prompted to open my phone and enter the same password to confirm that it is me logging into the bank app. I am allowed into the banks web app, where I tell it, yes it's me and I want to make that purchase.

It's at the stage where physical shops might actually be quicker and less hassle, especially if you have forgotten or mistyped the password and need to go through the process of resetting it.
