Instead of using a 2-Step Verification code to sign in to your G Suite account, you can tap a prompt that Google sends to your phone. This prompt is an easier and even more secure way of authenticating your account, and it respects mobile policies enforced on G Suite employee devices.
Until now, in order to receive Google prompts on a new device, you had to explicitly approve that phone when you first signed in with your G Suite account. With this launch, however, you can opt to get Google prompts on all of your devices automatically.
To get Google sign-in prompts on all of your phones, visit the 2-Step Verification page in My Account.
