Last Summer, Google started allowing users who have 2-factor authentication enabled to get notified and approve account access via a pop-up on their phone. The feature is deadly handy as it saves a lot of time over having to go over the Google Authenticator app and type in a six digit timed code. To this point, that pop-up provided basically a yes or no option but didn’t really give you any details other than someone was trying to sign into your account. That’s changing for the better as Google rolls out an update behind the scenes to improve the details you get when an authorization request is made.
First, if you don’t have 2-factor authentication enabled on your Google account, you can do that by going to myaccount.google.com. Navigate to Sign in Options and enable it. After that, you can add your phone to your account as being a device from which you can give authorizations in addition to the Google Authenticator app. Once you have it enabled, when you try to sign in from another device with your Google account, you will get a prompt on your phone to approve it.
