I use Duo Mobile for some accounts; it supports push. Definitely nicer than rushing to type a number in before the timer expires :)

There's a few minutes' slack so you shouldn't need to rush.

That is up to the website implementing the 2FA check. We only have tens of seconds slack.

definitely recommend duo push. you get the notifications, the multi-device support, and it's really easy to integrate into lots of things.

big fan
