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.
I enjoy using the Authenticator, I am using this for everything. However, when I am using it for work there is a teeny tiny annoying thing, when you type in the shown numbers you still have the option after you enter the correct number to reject the log in request. I think this has no sense. Why’d I enter the correct number and then just hit the reject button? It can only happen accidentally. Which only elongates the login process.Please consider the modify this to make the reject button inactive once a number has been entered since it proves the log in intention.Thank you!

When I tried to sign in to my teams account in the iOS app the system automatically went through to the authenticator app. Show me the number but I can’t be able to touch the number because pop up window doesn’t show me the number.
App of infinite loops for authentication
dshmusic
I don't know what's going on with this app, but I was able to use it with my own phone (iphone xr) properly and now with the new phone (iphone 15) and it's shiny new iOS it gets stuck in loops of authentications. I had to login six (!!!) times to my MS account to get this working. I have several accounts, tried with test tenants and same issue. Works well with old phone (I managed to authenticate via the old one in the end). As an extra feature this app keeps forgetting my accounts on the new phone even if it's synced both with MS and having a backup with Apple. When tried to auth to Teams it gets redirected to the Authenticator, then requested a login in the Authenticator instead of showing me the codes. Seriously?! This phone is also registered with the Authenticator, and I did the setup AGAIN, second time in two months! Very unhappy about this, causing me lot of overhead! This is an Auth app to provide me MFA login and this is what is causing troubles now! Not recommend to use this app if you are lucky enough not to have any mandatory company binding to Microsoft.
Useless

I don’t understand why everything is so complicated nowadays. In every website I have to change my passwords regularly nevertheless I have to select a password which contains 100 special characters and minimum 200 characters long which makes me have to write it down somewhere making this whole think less safe than back in the old days when I had my little pet as a password with small characters no numbers no special characters and I didn’t forget it. Now this application makes it even more complicated… please forget it and move on..
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.
