If you have an Apple device, it's pretty easy if you get the verification code via text messaging. I use my iPad for most everything. I can get texts and phone calls on my iPad. When a verification code comes in (I'm still on the verification page of the website), I make sure that the cursor is blinking where the code is supposed to be inputted, the code shows up as a text message but it also shows just on top of the keyboard, I touch it, and it fills in automatically. You just have to make sure that you have it set for your iPad to receive texts & calls from your iPhone settings. If that doesn't work, I do as others, check on another device for the code and input it manually.
