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.

Microslop
This is why they call it Microslop. Doesn’t recognize my account and asks me to use a code to sign in when I’m on the app, which is impossible. Would give zero stars if I could

No iCloud backup
Despite iCloud and iCloud keychain working perfectly, the authenticator back up option disappeared one day from settings and never came back.

Changing phone nightmare
This event will be hard for microsoft to live down. Every day, many people change phones but are not warned that authenticator still goes to the old phone. I have been without email for weeks.

Some flaws
This app is definitely flawed. You can’t easily log in to your accounts on a new phone. It asks for an approval or code which you can’t get because you can’t sign into the account. It’s a constant loop. Please add other ways to authenticate and log into accounts.

Pray you never get logged out
The Authenticator app is great until you get logged out. For instance, if you get a new phone. The app puts you in an endless loop of asking you to sign in and then asking for a verification code FROM AUTHENTICATOR!!! Which you can’t get into because you are logged out. It just goes on and on asking for a code. And forget calling Microsoft support. You only get an AI chat bot who doesn’t know what product Authenticator is so she literally just hangs up on you. This is truly one of the most frustrating experiences of my life.

This app is horrible
This app is laborious, stupid, and should not exist. Just another way for Microsoft to ascertain sensitive data and biometric information in the name of “security”

What a joke
I have to authenticate my Authenticator app which is impossible to do. And when I try calling the customer service number all I get is a robot and no matter what I say it always hangs up on me so I can’t even ever get a hold of a real person. I hate this app and the people who designed it.

To reset Authenticator app it requires me to validate with the malfunctioning Authenticator app. An endless do loop.
