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.
Five star review loses points for lack of back up instructions

App works great. I had to wipe my iPhone and reinstall all of the apps. All of my app data was lost and I was unable to get back into some of my accounts that failed to reload when the app reinstalled itself. Be sure to have multiple ways to access your account, including a mobile number and email address in case your device is stolen or wiped and you need multiple ways to receive codes for authentication
Better than 2FA, hands down
Joseph Schocker
If you read into the security flaws surrounding two factor authentication, you will realize that with good enough social engineering, and/or a hacker that knows what they’re doing, it can be bypassed. I highly recommend using an authenticator app, especially this one. You will have ease of mind, and your accounts will be as secure as they can possibly be.
Managing this app across phones and computers is sub par.
Chameleon Bearheart
Managing this app across phones and computers can be a hassle. I’ve been trying to migrate my account to my new phone for a year but have had to keep my old phone because it’s the only place the codes and online accounts have been linked to. Slowly but surely they’ve appeared on the auth app on my new phone after very odd trials and errors and ofc there’s no customer service to be found anywhere to help resolve this.
Too hard to retrieve your own password
Munky76
It signed me out on authenticator and I can’t remember my password and every time I try and all their steps to get my password back either wants to send me to my email which I cant access because I am signed out. Or it gets to the phone number section and tells me. This is not working try later and of course you try to call customer service but they just refer you to the website. So I haven’t been able to check my email in days which I need to.
We're always working on new features, bug fixes, and performance improvements. Make sure you stay updated with the latest version for the best authentication experience.
