Google has outlined a notable improvement to its two-step verification systems to make it easier for IT staff to protect user accounts.
Google said in a blog post that it will now make it possible for users to sign in to their accounts via two-factor authentication simply by approving a prompt on their smartphone.
"We know that security is one of your top concerns as a Google Apps admin and that many of you require your employees to turn on two-step verification (2SV) to keep their accounts safe," it said.
"There are multiple ways your end users can approve sign-in requests via 2SV - by tapping a security key, by entering a verification code sent to their phone or, starting today, by approving a prompt that will pop up on their phone."
The phone prompt option needs an Android Play Services update to work, and it's not possible to use a security key and a prompt at the same time. iOS users will need to install the Google Search app to enjoy the same experience. The prompt also needs a data connection to operate.
"Your employees can now choose any of these options in the Sign-in & Security > Signing in to Google > 2-Step Verification section of My Account. The Help Centre will be updated with detailed instructions soon," added Google.
"Instead of typing your password each time you sign in to your Google Account, you can get a prompt sent to your phone.
"Tap the notification from Google to confirm, and you'll be signed in quickly and securely. If your phone isn't nearby, you can select 'Use your password instead' on the sign-in screen."
Two-factor authentication can reduce this threat.
