New in version 5.8.0

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.

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.
MikeW2k on 5/16/2018
I’ve stopped receiving notifications. I have to open the app and copy the code and enter it into the login page. I used to get a notification I could just accept to login.
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!! 👍👍👍👍👍

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.
Works as advertised
jimct on 1/18/2018
We use this as MFA tool for logging onto our corporate network. Flawless and much better than the old text codes as no network connection is needed
Needs key generation
System2600 on 1/15/2018
Needs to be able to generate a key to work with more services. Similarly to how the Symantec app works.
Not secure
sixxt on 1/11/2018
This app works. But it is not secure. If I get a MFA notification on my lock screen I can allow the authentication without unlocking my phone. Fix now please
User-friendly and useful app
ethancdaniel on 1/4/2018
This is a very useful app for two-factor authentication. It’s as intuitive as possible and I’ve never had any issues with it.
No password protection
/criccraze/ on 1/4/2018
Surprisingly the most important app which is required to authenticate is open app. I failed to understand why this app doesn’t have password protection. What am I missing to understand here?
An Apple Watch app would be nice to have.
Birdsong Man on 1/4/2018
Wouldn’t have to fish my phone out of mypocket!
I don't understand this app
DavidCrosmierIII on 12/23/2017
This may be a useful program, but you'd never know with Microsoft's brief & non-descriptive description. Why should I download this app? Authenticate? Authenticate what? 3 stars is all I can give for such poor descriptions.
TheBattman on 12/18/2017
I don’t grasp why MS has chosen an additional app just for the sake of authentication.
Too frequent updates
danielkr_ on 12/15/2017
This app only does one job. Generate some numbers. Why does this need to be updated every other day?
Works great
mdbraker on 12/14/2017
Never an issue
MiaMc on 12/13/2017
I’m not able to set it up.
cgthomas1961 on 12/9/2017
This app doesn’t work very well. I can’t use it for getting to my Microsoft account!
Cannot select username to get code
jonmannon on 12/6/2017
Like the title says. This new update has made it to where I cannot select my username in order to generate a key code...isn’t that the purpose of this app?
Won’t even install
Fig204 on 12/5/2017
I’ve tried several times to install this app and it will not.
Add passcode option
Mr Kar on 12/2/2017
Add a layer a of security like a passcode option if someone click on the app they can see ur code and the account it’s linked too
What did you do?????
cltgt554 on 11/27/2017
Whatever you have recently done, has broken this app. And because of that, O365 Admin App no longer works either. Please get it fixed!!
Forgetful8765309 on 11/21/2017
Like most software nowadays, it is half baked. Does nothing. Uninstalled.
Excellent app, but…
Abraham Isaac Duran on 11/16/2017
It’s a great app, I like it a lot, but could you make it more secure? The login codes generated by the app could be used to sign in a critical site (like a banking account), so if you could add an option to provide an extra layer of security, that would be great. Also… what about being able te backing up to iCloud, so if you restart your device you won’t lose access to your codes?
Battery vampire
PunkRockPidgeotto on 11/14/2017
After I installed it I would be lucky to make it home from work before my battery died, after uninstalling it my battery life has returned to normal. Oddest thing is when I checked my battery usage it didn’t even show up, I never left it open or anything.
Apple Watch App
ian.guider on 11/10/2017
Should really have an Apple Watch app so that I can just quickly accept login requests
