Good app overall and I use it every day.My biggest wish is proper Apple Watch support. It would be incredibly useful to complete number matching directly from the watch when the phone is in a bag or not immediately accessible. Other authenticator apps already offer this, and I’d love to see Microsoft Authenticator support it too.

This has got to be the worst Authenticator app on the market. When it works it’s fine but try changing your device. Or worse change two devices at once which are the backup for each other you then get caught in the impossible loop. It’s highly frustrating. When are Microsoft ever gonna learn between this and Bing constantly harassing you? You can’t get away from them. They are the annoying little brother that will not go away. I love my PC. I hate Microsoft simple.

Despite having the Authenticator on my Microsoft account, somehow my account was still accessed from a foreign id, bypassing the choose a number system. I have since removed the Authenticator from all my apps, and changed to a more secure app. The only thing that saved me was the alert and recent activity notice that I could change my password and log everything out straight away so I didn’t lose anything.

I seriously can’t think of any justification for this app to exist when phone number, alternative emails, security questions etc all exists with other email providers. Difficulties I’ve encountered using this app: 1. When you switch to a new phone, the authenticatation will stay on the old phone and there’s no way to receive notifications or approve log in attempts unless you contact your institution. For an app that is the sole control for access as email it’s insane Microsoft still hasn’t figure out a way for users to move devices intuitively. This also means if you lose your phone you lose your access to your emails.2. When you authenticate your email that’s on the same phone as the authenticator app, a lot of the times the email log in pave disappears when you shifts app to look at the passcode. 3. If you’re logged out of both the authenticator app and your email there’s no way to log into your email. The “can’t use the authenticator app” option takes you to another option that requires the authenticator app. The “forgotten your password” option takes you to the authenticator app. I CAN’T LOG IN TO MY EMAIL BECAUSE I CAN’T LOG IN TO MY AUTHENTICATOR APP BECAUSE I NEED AN AUTHENTICATOR APP TO APPROVE MY LOG IN!!!!! This is insane. Why is there no option to approve email access through phone number in the big age of 2026

I’ve never written a review before, but this app is the most frustrating thing ever. It doesn’t keep you logged in and there are far too many steps for getting into your accounts. I understand the point is safety, but it just feels excessive. Furthermore, heaven forbid you get a new phone! Good luck trying to log into Microsoft Authenticator, because it won’t let you. It sends you round in circles. You can’t contact support from Microsoft because you need to login to your account. Which you cannot do, because you need Authenticator. Sorry! Gotta bother your IT department if you want to access anything at all.I couldn’t access my university emails or my work schedule, because Authenticator wouldn’t let me use it. This caused me a lot of stress for days, until my IT departments fixed it.It’s honestly embarrassing for a company such as Microsoft to have an app like this. It wouldn’t matter so much if it was insignificant, but this app is literally required if you want to login to your account. It’s awful, and I wish I could give it zero stars. Do better.

Latest update fails to tell me in settings about if my account is backed up. No options at all in settings claiming if my account and all its codes are being backed up to the cloud. I wish I went with another option. It was great and this latest update is the last stop. I will be moving away from MS Authenticator if there’s no way of telling if things are being backed up in my iCloud like it use to say which date I created a backup and when it was last updated. Please for the love of god implement that feature so we can be more transparent about successful backups and ability to transfer over to a new primary device. Why Microsoft????

I want to meet the intellectual genius behind this incredible innovation and (after a healthy dose of throat punches and violent attempts on their life) ask this behemoth of knowledge why tf they thought it would be a cracking idea to not only have this app required for signing in to my account every single time, but also needing this app to sign into this very app itself which, to those of you who do not possess the sheer brain power of those behind this divine creation of god (which surely will be none of you), you may realise that this is a bootstrap paradox that would bewilder Doctor Who. Remember when you could have a password that would let you sign into your account? Those were the good old days. Now you need 20 verification messages and 40 separate apps just to check an email from your lecturer only to find out that you’ve missed the deadline set because you’ve wasted hours of your life constantly on the phone to IT support people. I would say that they only make these useless apps just to give these Microsoft employees something to do but clearly not as no one seems to be making any steps to improve these services. And how is this rated 4.7/5? Maybe all those Bill Gates microchip vaccine people have a point because surely this has to be a brainwashing scheme. Or maybe it’s just me. Maybe the failure to sign into this app is a reflection of my lack of technological abilities. Maybe I’m insane. All I know is this app leaves me feeling that maybe all the serial killers in human history had a good thing going.

Having migrated from an iPhone X to an iPhone 13 over the weekend, to my horror I discovered that the Authenticator app was no longer working as it should be an all of my passwords were not performing as they should wear many had been lost. Worst of all, I’ve been locked out of my email account for over a week with very poor support from Microsoft considering they have all of the necessary details to easily identify me as a legitimate user of the account and the administrator. Has been exceptionally disruptive and of course has many on effects with other credentials that go back to my core email including resetting passwords and applications that are equally not working properly after the migration. It is about time Apple, Microsoft, and Google stop sabotaging each other and started to work seamlessly as they should or maybe the merge of monopoly commission should break them all up and enable other players to come into the equation who are far more responsive and agile. I’m disappointed to have to report that the issue has been outstanding for a week and I’m continue to be locked out of my email account.

I was very happy with Authenticator until I read about the new wave of phones being stolen after acquiring the iPhone’s passcode such as shoulder surfing. App Lock in settings uses Face ID which is fine, but defaults back to the iPhone passcode if Face ID fails. Worse still is that Authenticator has all your website passwords for any Microsoft account that has been setup in the app. If you have multiple Microsoft accounts the app allows you to switch the account used to sync the passwords without requiring any re-authentication. Most apps that take security serious do not allow this to happen. Instead, they require app specific authentication on Face ID failure. Alternative Authenticators such as Authy and 2FAS prevent this from happening as do banking apps. Is it right that Microsoft is not willing to protect your information beyond relying on Apple’s security. A safe inside your house can protect your valuables.

I think they even used the Authenticator against me to have easier access to my account even when I changed the password, I don’t know for sure though. All I know, is that while using the Authenticator and updating my password multiple times, it still happened to me. It’s a pretty scary experience to have, when they even send an email to your hacked account (like emailing themselves), and especially scary because I thought the Authenticator would make it impossible to do it to me. I also find it scary how there’s bots trying to constantly hack accounts, and I wish things would be safer online. (It showed me even more people trying to login when I had the Authenticator installed, it looked like it was protecting me, but it didn’t in the end.)I doubt anyone would believe me, because there’s mostly 5 star reviews. But that’s what happened, despite keeping it all updated. I had to recover my account and I hope it’s safer now.
