Frequently asked questions

What data does the Authenticator store on my behalf and how can I delete it?

Microsoft Authenticator stores the account information you create when you add an account. When you use Authenticator, a diagnostic log is created for debugging purposes and stores useful data in helping Microsoft diagnose any unforeseen issues. You can access the log data by opening Help > Send Logs > View logs.

You can delete the data by deleting the account tile. Deleting the account tile also deletes all the account information being used by the application including the logs.

What are the codes in the app for? Why does the number keep counting down?

When you open the Microsoft Authenticator app, you see the accounts you've added and a six- or eight-digit number by each of them. You might see a 30-second timer counting down.

These codes are used when you sign in to your account. After you enter your username and password, you might be asked to enter a verification code. Open the Microsoft Authenticator app and copy the code that's currently showing. Enter that code in the sign-in page to finish.

The reason that the codes change every 30 seconds is so that you never use the same code twice. It's not like a password that you're supposed to remember. The idea is that only someone with access to your phone knows your verification code.

The codes don't require internet or data, so you don't have to worry about having phone service to sign in. When you close the app, it doesn't keep running in the background and it doesn't drain your battery. You can close the app and ignore it until the next time that you sign in.

I only get notifications when I have the app open. If the app isn't open, I don't get any notifications.

If you get notifications, but they don't make noise or vibrate despite your ringer being on, first check the app settings. Enable the app to use sound or vibrate with its notifications.

If you don't get notifications at all, check the following cases:

  • Is your phone in Do Not Disturb or Quiet mode? That mode can keep apps from sending notifications.
  • Can you receive notifications from other apps? If not, there may be an issue with the network connections on your phone, or the notifications channel from Android or Apple. You can address the first option in your phone settings, but you may need to talk to your service provider for help with the second option.
  • Can you receive notifications for some accounts on the app, but not others? If yes, remove the problematic account from your app and add it again to enable push notifications.

If you tried these troubleshooting suggestions but are still having issues, you can send your logs for diagnostics. Go to the app settings, then select Help & feedback and Send logs. Then, go to the Microsoft Authenticator app forum and let us know what problem you're seeing and what steps you've tried so far.

I'm already using the Microsoft Authenticator application for verification codes. How do I switch to one-click push notifications?

Approving a sign-in through push notification is only available for personal Microsoft accounts or work and school Microsoft accounts, not for third-party accounts like Google or Facebook. If you have a work or school Microsoft account, your organization can choose to disable this option.

If you use a Microsoft account for your personal account and want to switch over to push notifications, you need to add your account again. Re-register the device with your account, and set up push notifications.

If you use Microsoft Authenticator for your work or school account, then your organization decides whether to allow one-click notifications.

Do one-click push notifications work for non-Microsoft accounts?

No, push notifications only work with Microsoft accounts and Azure Active Directory accounts. If your work or school uses Azure AD accounts, they may disable this feature.

I got a new device or restored my device from a backup. How do I set up my accounts in the Microsoft Authenticator app again?

If you’re running an iOS device, have turned on Auto Backup, and have created a backup of your accounts on your old device; you can use that backup to recover your account credentials on your new device. For more info, see the Backup and recover account credentials with the Microsoft Authenticator app article.

I lost my device or moved on to a new device. How do I make sure notifications don't continue to go to my old device?

Adding the Microsoft Authenticator app to your new iOS device won't automatically remove the app from your old device. Even deleting the app from your old device isn't enough. You must both delete the app from your old device and tell Microsoft or your organization to forget the old device and unregister it from your account.

  • To remove the app from a device using a personal Microsoft account. Go to the two-step verification area of your Account Security page and choose to turn off verification for your old device.
  • To remove the app from a device using a work or school Microsoft account. Go to the two-step verification area of your MyApps page or to your organization’s custom portal and choose to turn off verification for your old device.

How do I remove an account from the app?

  • iOS: From the main screen, swipe left on an account tile. Select Delete.
  • Windows Phone: From the main screen, select the menu button, then Edit accounts. Tap the X next to the account name.
  • Android: From the main screen, select the menu button, then Edit accounts. Tap the X next to the account name.

If you have a device that is registered with your organization, you may need to complete an extra step to remove your account. On these devices, the Microsoft Authenticator app is automatically registered as a device administrator. If you want to completely uninstall the app, you need to first unregister the app in the app settings.

Why does the app request so many permissions?

Here is a full list of permissions that can be asked for, and how they are used in the app. The specific permissions you see depend on the type of phone you have.

  • Camera: Used to scan QR codes when you add a work, school, or non-Microsoft account.
  • Contacts and phone: Used to simplify the process by finding existing accounts on your phone when you sign in with your personal Microsoft account.
  • SMS: Used to make sure your phone number matches the number on record. When you sign in with your personal Microsoft account for the first time. We send a text message to the phone where you downloaded the app that includes a 6-8 digit verification code. Instead of asking you to find this code and enter it in the app, it's found in the text message for you.
  • Draw over other apps: The notification you get that verifies your identity is also displayed on any other app that might be running.
  • Receive data from the internet: This permission is required for sending notifications.
  • Prevent phone from sleeping: If you register your device with your organization, your organization can change this policy on your phone.
  • Control vibration: You can choose whether you would like a vibration whenever you receive a notification to verify your identity.
  • Use fingerprint hardware: Some work and school accounts require an additional PIN whenever you verify your identity. TO make the process easier, we allow you to use your fingerprint instead of entering the PIN.
  • View network connections: When you add a Microsoft account, the app requires network/internet connection.
  • Read the contents of your storage: This permission is only used when you report a technical problem through the app settings. Some information from your storage is collected to diagnose the issue.
  • Full network access: This permission is required for sending notifications to verify your identity.
  • Run at startup: If you restart your phone, this permission ensures that you continue you receive notifications to verify your identity.

Why does the Microsoft Authenticator App allow you to approve a request without unlocking the device?

You don't have to unlock your device to approve verification requests because all you need to prove is that you have your phone with you. Two-step verification requires proving two things – a thing you know, and a thing you have. The thing you know is your password. The thing you have is your phone (set up with the Microsoft Authenticator app and registered as an MFA proof.) Therefore, having the phone and approving the request meets the criteria for the second factor of authentication.

What does the lock icon in the account list mean?

The padlock icon indicates that the device is registered in Azure AD and registered to the account. Device registration for iOS takes place during Microsoft Intune enrollment.
