Approve or deny sign-in requests to your Microsoft account using Android
If you want to enable two-step verification for your Microsoft account, Microsoft pushes you to install and use their own Microsoft Authenticator app. It is available for Android, iOS and Windows 10 Mobile. If you have a smartphone with this app installed and configured, you get the benefit of signing in faster, without having to type the security code that is required for two-step verification. You get a notification on your smartphone with two options: Approve or Deny. Tap one of them and you are done. Here's how to set up the Microsoft Authenticator app on your Android smartphone, so that you can quickly approve or deny sign in requests to your Microsoft account:
Step 1: Download and install Microsoft Authenticator from the Play Store
The first step is to download and install the Microsoft Authenticator app from the Play Store. You can find it here.
Step 2: Start the Microsoft Authenticator app on your Android smartphone
Go to the Apps list and launch the Microsoft Authenticator app. If you are like us, you have other Authenticator apps too. Therefore, make sure that you tap on the shortcut that looks like the one highlighted below.
Once started, the Microsoft Authenticator asks you to add accounts and looks similar to the screenshot below.
Step 3: Add your Microsoft account to the Microsoft Authenticator app
Press "Add Account" and choose the type of account that you are adding. If you want to add a personal Microsoft account, tap "Personal account."
If you have any Microsoft accounts already registered on your Android smartphone or tablet, the app will show them to you.
Tap the account for which you want to enable two-step verification using the Microsoft Authenticator app. If the account that you want to add is not shown, tap "Add an account."
Type the e-mail for your Microsoft account and press Next.
Enter the password for your Microsoft account and press Sign in.
At this step, if you have set up some form of two-step verification in the past, through e-mail or SMS, you will be asked to enter your security code. After you enter it, you are shown the "Welcome to phone sign-in!" screen. You are informed that the next time you or someone else signs into your Microsoft account, you will get a notification on this app to approve or deny.
Tap "Got it" and you are done. The app now shows the Microsoft account for which you have added the temporary two-step verification code.
How to approve or deny logins, using Microsoft Authenticator
The next time you or someone else signs into your Microsoft account, from another browser, computer or device, the Microsoft Authenticator app will show a notification on your Android smartphone, like the one below.
In this notification, you see the two-step verification security code and two buttons for denying or approving the request. If the app is open while you sign in, the notification will look like the screenshot below.
If you press Approve, you can sign in. If you press Deny, the login is refused, and you or the person trying to access your Microsoft account is denied access. If you encounter sign-in requests from someone other than yourself, you must change your Microsoft account password immediately.
