New in version 5.9.14

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.


Sign in is easy, convenient, and secure when you use Microsoft Authenticator. Use your phone, not your password, to log into your Microsoft account. You simply have to 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'll have access to all your Microsoft products and services, such as Outlook, OneDrive, Office, and more.

Microsoft Authenticator also supports multi factor authentication for work, school, and non-Microsoft accounts. The app provides a second layer of security after your password. When logging in, you'll enter your password, and then 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 verification code generated by the app. 

Sometimes your work or school might ask you to install the Microsoft Authenticator when accessing certain files, emails, or apps. You will need to register your device to your organization through the app and add your work or school account. Microsoft Authenticator also 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. Because Microsoft Authenticator supports single sign-on, once you have proven your identity once, you will not need to log in again to other Microsoft apps on your device.

No use for my iPhone as it won’t recognize the code Microsoft sends me to set up the app!!
grangergal on 8/15/2018
Just downloaded the app and tried three times to input the codes I was sent but novo!!
Hate It
MCD4x4 on 8/12/2018
The way this app works is like no other. What a pain in the
juniortsf on 8/11/2018
The restore feature is broken other than that it works just as intended
It’s a bunch of garbage!
ValdostaDM on 8/10/2018
I’ve been trying to load this app and it just keeps endlessly cycling and changing numbers! All I wanted to do was change my password because the system said it didn’t recognize it and it was making me ask for and type in all these ridiculous codes. This is hell on earth!!!!
Very vague
sepeeed on 8/10/2018
Very vague in telling you what you need to do or be expecting may or may not reliable enough Also I’m experiencing problems w it being reloaded to my phone from cloud ...
Backup is gone
staunchnortheasterner on 8/6/2018
It says there’s no backup on my iCloud account even though there is.
Works great
Gautey2408 on 8/1/2018
It works fine for what it is intended to.
MS launches yet another piece ‘o poo
Radio Recording Guy9 on 7/31/2018
It’s like these guys never bothered using their own apps. JUST TO SET UP A PIN LOGIN FOR MY LAPTOP, I had to give MS my mobile number (that will never happen), or authenticate through their app. 1) the app gives me the option of turning off notifications, so I turn them off. 2) it directs me type in a code from the app. But then it doesn’t work because notifications must be turned on. 3) I turn on notifications and try for several minutes to get the code accepted. Error message: you have used this code before. No further instructions. 4) I step back and generate a new code and try to submit this. Nothing happens, no message, no instructions. 5) Finally I give up and supply my work phone for authentication. MS must have a phone. 6) Finally, after ten minutes of struggle, my laptop is authenticated for use of a PIN for log in. Is there anyone else having a problem with MS’ crappy software? There is no evidence they have ever tested this app. What an utter piece of crap. MS should be ashamed.
Worst. Do not turn this on.
Hherrig on 7/28/2018
Got a new phone and something didn’t transfer with the Authenticator. I have been locked out of my email for over 60 days & counting and this has been a nightmare. When will I ever get access to my email again.
Newest version deletes ALL accounts upon re-launch
ENAJonas on 7/24/2018
Unbelievable. Did you not test this at all?!?!?
Not the best
User65322 on 7/19/2018
It blows my mind that some people say they trust Microsoft more than Google. News flash, google has had Authenticator for years. Microsoft didn’t have full SSL encryption for mail or 2 factor authentication until years after Google offered it. This is merely a poor copy of the Google Authenticator app - the original and the best.
Love it
Omnidread on 7/16/2018
It’s a solid app that literally does exactly what says it will do for you!
Doesn’t work for me.
ChuckBowie on 7/14/2018
Complete waste
anon0369 on 7/11/2018
If your changing your phone number and don’t already have an existing Microsoft Authenticator setup on another device then you will not be able to proceed. End of story. Horrible...
hitthegas1 on 7/10/2018
I have never heard of this app until it popped up a message on my device stating that it was about to install itself from the App Store. This message appeared multiple time per day for the past five months despite hitting cancel every time. I even tried allowing it to install once and then I went in and removed my information that it somehow already had without me entering it followed by quickly deleting the app. That’s pretty fishy right? Smells like a scam to me!
lafapilot on 7/9/2018
This app will be on your iPhone FOREVER. It is not possible to uninstall it and it will notify you every couple hours to reinstall it.
Skybugloves on 6/30/2018
This app never notifies me if I’m trying to sign in so I can’t sign into my freaking school account. This is all dumb and I hope literally no other company or school requires you to download this awful app. Which by the way, if you have trouble with it, the people who made the app do not help you at all. You have to go to whoever made you get the stupid app. It’s all dumb. And it doesn’t work. Even if I manually generate a code, it just doesn’t accept it.
Updates with garbage release note
Lt Gizmo on 6/26/2018
Look at the update history and we would see the same release notes that tells the user absolutely nothing. How did this kind of behavior gets pass review is total mystery.
Excellent app, but…
Abraham Isaac Duran on 6/22/2018
Why don’t you add an option so one has to use Touch ID in order to open the app and access the codes?
Thank you
Fhghuvhjxbhvx on 6/15/2018
Thank you for continually trying to invent ways of increasing account security.
Solid. But needs spit-polish
CyberData4 on 5/26/2018
The core functionality of the app is rock solid. It works. Every time. Not one crash. But my problem is all this time I see no spit polish with some nice to have features. Example 1: Now, this is petty. Tom Petty. But for accounts that don't automatically pull in an avatar image ID like the option to set it myself. When I click edit I should be able to click each image and set it from photos. Example 2: For an app that provides security why can't I set a password or touched for opening the app? Like everything else I can enable this with the understanding that it's my responsibility to secure said password to access my app. This way no one can snatched my phone when it's on but unlocked at my desk and I'm in the restroom. It's the little quality of life things that are missing that could really set this app apart from the competition. That being said I trust MS with my data more than Google so I'll keep this. Good job. But please consider these changes.
Nice but need little feature
Vic@395004 on 5/21/2018
I really liked this app but if you can support Apple Watch that will be good.
Does not work amore
WhiteTigreNV on 5/15/2018
After the last update it does not notify my device that my account is being logged into. So I am unable to approve the logon.
Great job on the update!
Wesley Brilhante on 5/6/2018
Great update with the backup option!
Better than Google
High on lifeeee on 5/5/2018
Love this app. I started using it on 5-3-18. World great and no issues. Backup in iCloud is perfect. Feature request: would be even better to have TOUCH ID option to open the app for added security. Issues: there would sometimes be no notifications or a delay, both in the app or when the phone is locked.
Great But
Dookie 2x on 4/29/2018
Love it for how it works as a remote Authenticator for OneDrive & Outlook, and especially for work to authenticate with TouchID when logging in to work resources. BUT - really frustrated by how you lose 2 factor or step linkage to services when you have to restore your iPhone (either from having to erase or moving to a new iPhone) and now I’ve lost login access to some services I used it with for 2 factor. One in particular doesn’t even offer email temporary recovery so I have to completely wipe my settings and information to re-establish access.
Backups are here
dstefan519 on 4/27/2018
Being able to backup and restore mfa is a big win
Backup feature doesn’t work
sdoregon on 4/27/2018
Don’t rely upon the new backup feature. It does not work.
Backup and Recovery!
Psst!! on 4/27/2018
Finally! Backup and Recovery was what I most needed for a long time now. Thank you!! 👍👍👍👍👍

Kellye Robinette Anwar. on 4/17/2018
When I try to log into my outlook email it asks me to tap the code in the Authenticator but when I open the Authenticator it opens with a different number. I entered my outlook info in the Authenticator and it doesn’t work
Tuprhasan on 4/5/2018
yes help
Add new function
AaMir-s on 4/4/2018
Plz add Touch ID or Passcode before opening the app.
Works alright, would love Watch compatibility
forkies on 4/4/2018
Will support for Apple Watch be coming soon?
Saved me from hackers
MsDowser on 3/30/2018
Debating on getting this? I did for a long time as I had two step verification. Got this and realized hackers in Romania, Thailand, Korea and more had been using my email address. Who knows what else they done around the globe? Now their sign-in attempts on my email account name are all rejected.
Potentially disastrous
perkedel on 3/29/2018
App works great, but one major problem is that it doesn’t allow its data to be backed up to iCloud/encrypted iTunes back up. So if you do a restore, you lose all your 2FA keys even though all your other apps and its settings are restored, except this one. It’s a problem where you can get locked out of all your accounts. Google Authenticator does not have this problem, have switched to it today because of that massive problem I encountered with missing keys after a restore from backup. I hope the devs are listening!
Never had a problem
Brian dead riff on 3/27/2018
I split my keys between a few apps, and this one has the least number of issues, so far.
Where’s facial recognition support?
Buddhastyle on 3/16/2018
Never had a problem with this app until I bought the iPhone X. Now I need to use my pin because the device has no fingerprint option and the app doesn’t support facial recognition (which is apparently more secure). Please add. Otherwise, this app works great!
Takes a lot if tries to make the notification appear.
A. C. I on 3/14/2018
I have tried few times, but didn't get anything. Then decided to turn off wifi and see if on cellular data the notification would go through and it did. WiFi has an excellent internet connection, so I don't really know what is causing this notification delay or the multiple tries.
Won’t download
skayc56 on 3/12/2018
It shows just a little bit more to get to fully downloaded but will not complete the task
Less awful than using those old RSA hard tokens
meltmade on 3/12/2018
The ability to copy and paste verification tokens is what lifts this app up out of the sinking swamp of annoying corporate authentication schemes and into the abysmal humid rotten atmosphere roiling just above it. I'm also tired of every Microsoft application out there now referring to itself as "we." Stop it.
How to delete Authenticator app
1937:: on 3/11/2018
Terrible this app has taken over my iPhone. Microsoft support cannot help me delete it! Do NOT download thus app. You will regret it IMMEDIATELY! Microsoft provides NO HELP!
The Gold Standard
BlazinBear on 3/10/2018
If every authentication app worked like this, they might be used more. This app is by far more useful than the Google competitor. Having to use both, since some accounts only work on one or the other, I much prefer to use Microsoft. The simple act of hitting approve or selecting a number makes signing in a breeze. This is what the future of logging in should be like.
Typical Microsoft.
nira c on 3/10/2018
Instead of supporting already existing Authentication apps. Create a code that cannot be used by anyone else then force people to download their app. The app crashes all the time. They don’t have Apple Watch support. I have to take out my phone every time I need a code. Fix it or support other authenticator apps.
Needs Face ID support
mercutio on 3/10/2018
Great app, but you should be able to password protect it so other people who might use your iPhone can’t open it and access your codes. Face ID, Touch ID, and passcode support is a must.
Not Necessary!
Bigg dude on 3/9/2018
This app is really not necessary, that is if you stay on top of your accounts. It eventually gets annoying with the extra steps and starts to be a hindrance. Stay diligent don't become complacent, and don't download this app it's simple as that. This app does what it claims to do and would be very helpful to someone who can not stay focused. To those who are completely aware that remain focused this app is a time consuming step that's avoidable.
Simple and Effective
Goatllama on 2/19/2018
Has always worked flawlessly for me. Would be great to have the option for an extra passcode lock for the app, though.
One star
N328KF on 2/2/2018
One star due to useless update summary.
Resets every update!
BanuGhassan on 1/27/2018
Since inception whenever I have all accounts with their verification setup and on standby... here comes and update, Great! Open to see app, everything gone and have to redo it all over again. Every update!? I stopped using this app and found an alternative from a company that sounds like booble.
How about an Apple Watch component?
Delta5 on 1/20/2018
Does what it’s supposed to do. How about adding an Apple Watch version too?
Not Unique
DK1943 on 1/18/2018
This app cannot coexist with Google’s Authenticator. Upon installing, each overwrites the other.
