Description

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.

Great App until it Loses Your Backup

After reinstalling the App due to changing iPhone I initially had no issue. I started recovery and all my credentials arrived. That was however until I needed to 2FA an account only to find only my Microsoft account being listed.

Seriously, between this App and Microsoft’s OneDrive, which always dumps my files, which in regards to OneDrive I have become so used to the loss of my files I now have the files updated to a portable drive. Which makes you wonder what the hell is the point in having files saved to iCloud. You can barely call anything, files, 2FA apps, et cetera et cetera any safer than an old school floppy drive.

Vulnerable to Passcode Attack

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.

Despite having the Authenticator, my account was still hacked.

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.
