Microsoft Authenticator 4+

Protects your online identity

Microsoft Corporation

    • Free


Use Microsoft Authenticator for easy, secure sign-ins for all your online accounts using multi-factor authentication, passwordless, or password autofill. You also have additional account management options for your Microsoft personal, work or school accounts.

Getting started with multi-factor authentication

Multi factor authentication (MFA)provides a second layer of security. When enabled, during login after entering your password, you’ll be asked for an additional way to prove it’s really you. Either approve the notification sent to the Microsoft Authenticator, or enter the one-time password (OTP) generated by the app. The OTP codes have a 30 second timer counting down. This timer is so you never have to use the same time-based one-time password (TOTP) twice and you don’t have to remember the number. The OTP doesn’t require you to be connected to a network, and it won’t drain your battery. You can add multiple accounts to your app, including non-Microsoft accounts like Facebook, Amazon, Dropbox, Google, LinkedIn, GitHub, and more.

Getting started with passwordless

Use your phone, not your password, to log into your Microsoft account. Just enter your username, then approve the notification sent to your phone. Your fingerprint, face ID, or PIN will provide a second layer of security in this two-step verification process. After you’ve signed in with two factor authentication (2FA), you’ll have access to all your Microsoft products and services, such as Outlook, OneDrive, Office, and more.

Getting started with autofill

Microsoft Authenticator app can also autofill passwords for you. Sign-in on the Passwords tab inside the Authenticator app with your personal Microsoft account to start syncing passwords, including the passwords saved in Microsoft Edge. Make Microsoft Authenticator the default autofill provider and start autofilling passwords on apps and sites you visit on your mobile. Your passwords are protected with multi-factor authentication in the app. You will need to prove yourself with your fingerprint, face ID, or PIN to access and autofill passwords on your mobile. You can also import passwords from Google Chrome and other password managers.

Microsoft personal, work or school accounts

Sometimes your work or school might ask you to install the Microsoft Authenticator when accessing certain organization resources. You will need to register your device to your organization through the app and add your work or school account. Microsoft Authenticator supports cert-based authentication by issuing a certificate on your device. This will let your organization know that the sign-in request is coming from a trusted device and help you seamlessly and securely access additional Microsoft apps and services without needing to log into each.

Best app with problems on new iOS

Hi I love your app. Especially notifications and opportunity to confirm authentications on watch. But after last iOS and watchOS update the watch part of the app is not working. It doesn’t see any account from iPhone app so notifications are not working to. I was doing factory reset after iOS update for phone and watch. And recover data in your app from menu of the app. App is working great only watch part stopped work.
I hope you can fix it soon.
Good luck and keep doing best authorization app. 👍

You really need to add Touch ID, because it can be so much safer.... (otherwise 5/5 stars...)

Horrible UX.

I’m almost convinced that you are doing worst UX apps for iOS. I know what it’s not true.. but the whole authentication experience with Microsoft flow, starting on MacBook pro and going through mobile app, and then ends up on Macbook, it’s a huge pain for the user.
My employer forcing me to do that, only because of the license and security. But one day I will be in a position where I will have to make a decision if I continue as a company to pay for your services, and I will definitely will look for an alternatives.

All the apps that user can use on iOS devices having issues and defects that are making it horrible UX experience. Not only the authenticator.
