Changing default phone for Google login device So the following annoying thing happened to me. I wanted to print some documents at my local printer shop from my Google Drive. 

However, Google decided I can't log in because it doesn't recognize my device. It wanted me to go to my phone and get a security code. 

However, I didn't have the phone Google thought to be my default phone (Android device) and didn't allow me to choose my other phone, which I actually use (an iPhone).

Just like that, I was locked out of my own account, unable to print anything. So my question is:

Where can I change my default phone so it sends a push confirmation to my iPhone when I log in from an unknown device instead of the Android?
Go to myaccount.google.com, sign in and click on Sign in and Security.

Scroll down and go to Account Recovery Options and click on Recovery Phone

Add/remove the phone numbers according to your preferences.

Then go back, scroll down and click on Recently Used devices and remove all the devices that are not in use. If your Iphone is not displayed here then make sure that you've signed in in your IPhone with Google Account.
