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.
Microsoft Authenticator Negative Reviews
Not working AT ALLWhen I sign in to my school account and it tells me to enter a certain number on this app, NOTHING shows up on the app for me to put in that stupid number! My app is up-to-date and my wifi is working just fine. IDK why I have to have this app from the beginning, ugh..Char9919Version: 6.7.15
AnnoyingCareful it doesn’t delete your account because you will never be able to access that again. I got a new phone and the backup didn’t work properly so I wasn’t able to access any of my accounts until I was able to get to my old phone which still had the saved info.Cutebear9811Version: 6.5.80
Watch OSWatch approval stopped working for me. I only can approve from the phone..CJiggyVersion: 6.4.26
Causes phone to run very hot.Whenever I have to use this and then leave it running in the background it causes my phone to excessively heat up and drains the battery. If I remember to close the app and this doesn’t happen..WreakingHavocVersion: 6.4.16
JunkWhen signing into the Authenticator app, the app asks to use the Authenticator app to approve the request.

TerribleThis app is useless and doesn’t work at all, I can never log into my account cuz I need a code but when I open the app, I never receive any code to log in no matter what I do. I need to log in my university student account Microsoft DO SOMETHING!!!!.Gaby VitelloVersion: 6.8.13
WhatTry to login my email which pushes me to open the authenticator app to verify my identity and then once in the app it tells you to go to the authenticator app to and enter the code that’s on your screen except your already in the app sooooo….Kat_mom21Version: 6.7.13
I hate this appYour apps on the phone really sucks. I was trying to open my school account. Then my school will direct me to your apps and then your apps will ask me codes without seeing the code first and the only option I have are. If it’s not me and the yes that doesn’t work because I have to provide codes first..Unkown tapperVersion: 6.7.7

Horrible.Viscous circleagainVersion: 6.8.16
SuxxCan y’all fix the app already. Every time I try to log in it says use the code sent to my authenticator app so I open it and there’s no code and it says no new notifications. It’s been doing this for 6 months and apparently I’ve ran out of verification codes to send to myself because that’s the only way to confirm so I am now locked out of my university classes.
Might be the worst app I’ve ever used..IPod touch 5 generationVersion: 6.7.15
Worked great until last updatesPush notifications no longer work on my iPhone or my Apple Watch since the Last sets of updates. The Apple Watch notifications hasn’t worked in months. The notifications are set to on for this app. Come on Microsoft..IngykVersion: 6.5.80
Not GreatWorks well enough for generating/storing 2FA codes but there’s a lot of problems.
- Backing up is unclear and extremely unreliable.
- Apple Watch support doesn’t work, either fix it or kill it.
- App is overly confusing to use, especially with multiple Microsoft accounts (Personal and a Work account).
I expect way more, the app isn’t terrible but it certainly is the Windows Vista of available Authenticator apps..DjtripdVersion: 6.5.86
Can’t log inGot a new phone and now I’m logged out the Authenticator app. Now I can’t access any of my school work or my school email because there no way to log back into the Authenticator app on your phone..Please_help_.meVersion: 6.8.39
HORRIBLE APPIf you try to log in on the app it will ask you to use a verification code in the app (which you cant get because you cant log in) and there is 0 support from microsoft at all, no numbers or useful information anywhere.Yeikwn wVersion: 6.8.38
TerribleProbably one of the worst apps that you can download on the App Store, extremely disappointing coming from Microsoft, this goes to show how little the company cares as the app as basic issues that still haven’t been resolved. I recommend everyone to download a different authentication app..Chubby bunny🍄🟫Version: 6.8.27
FIX YOUR APPJe dois me connecter sur mon compte collegial teams,mais après avoir entrer mon mot de passe sa me demande d’entrer un code sur cette app, mais rien apparait.

Bravo microsoft sa travaille fort👏🏼.Love jdmVersion: 6.8.27
Poorly designed and not operationalI’m am horrified at the poor design of this app, and even more so by the lack of support. This app is a much greater hindrance than it is a help and when things go wrong, you’re on your own to try to resolve them. Could not be more disappointed..BooMicrosoft!Version: 6.8.27
This app sucksIt’s hard to use. no videos help. On the rare occasion it’ll work, but otherwise it’s overall a horrible app..Jadenn hearnVersion: 6.8.27
Confusing and IrrationalTransferring my business account over to Microsoft to use email handle and One Drive is the single most worst tech experience I’ve had, and I’m fairly technically literate.
The Authenticator App system is completely broken, inefficient, and senseless. Nothing is simple, any adding of apps or password resets results in incredible amounts of frustration with a circular loop of getting nowhere.

Mal faitJ’ai besoin de cette application afin de me connecter à mon compte étudiant Microsoft, mais rien ne fonctionne. Aucun code n’apparaît dans l’application et aucun code QR. J’ai vraiment tout essayé. Je ne comprends pas pourquoi il faut passer par cette application pour la vérification du compte. De plus, il n’y a aucune explications ou aide sur l’application..2144dedeVersion: 6.8.14
Last Update Broke ItThe latest update will not allow the App to work. It wants me to complete the setup with no explanation. It worked for years, suddenly this message comes up when trying to access sites with passcodes that are in the Authenticator App!.KmfmfVersion: 6.8.10
Microsoft appSo stupid that I need this app to sign into my school email and be able to sign up for my classes. No other way to do it. Upgraded to a new phone now it won’t let me sign into the app on my new phone and is only giving me a 2 digit passcode when you need a 6 digit passcode? Microsoft support is useless so I am having to keep my old phone to hopefully be able to login in. Such a useless stupid app..Jki77777777Version: 6.7.13
Annoying!Now it’s not enough that I authenticate a request. I have to authenticate my authentication with my Touch ID. And then half the time, it refuses to accept the authentication. There is such a thing as exaggeration, guys..JorgeFromMontrealVersion: 6.4.22

Login loop - very frustrating experience.Microsoft Authenticator just locked me out of my own admin account after I changed phones. No warning, no easy recovery, and no backup unless you set it up in advance. The app shows my account, but doesn’t generate any code, so I’m stuck in a login loop with no way in.
For something this critical, the lack of a simple recovery option is unacceptable. If you’re using this for business, make sure you have multiple admins and backup methods, or you risk getting completely locked out like I did.

Inutile, perte de tempsJe déteste que deux de mes employeurs utilisent cette méthode de vérification. L’application Bug, sans cesse, elle efface nos identifiants constamment, ne reçoit pas les codes ou n’en affiche pas non plus. Bref, chaque fois, je dois me battre avec les IT pour tout réinitialiser, c’est vraiment frustrant et ce à chaque mise à jour ou changement de cellulaire, c’est complètement ridicule!.CynalenaVersion: 6.8.44
Horrible cycleI can't log in to my account without being logged into the authenticator app, and I can't log in to the authenticator app without first being... logged in to the authenticator app. I am stuck in a horrid loop that is typical of microsoft office and microsoft outlook.

Zero StarsI would give this app zero stars if I could. This app is beyond difficult to use. I have had to reach out to my IT department many times to reset this app. It’s unnecessary, full of bugs and glitches. Don’t even try to call Microsoft for help, they don’t have any human agents anymore and their AI agent is useless. Absolute waste of time..CourtneyMartin99Version: 6.8.43
