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.
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.

Keep in mind a major concern when choosing to give the a shared security clearance for each factor. Example: Someone who chooses 2FA via SMS that happens to be Google Voice and also stores password to Google Chrome becomes vulnerable to a massive breach. 1 hack has potential to clear authentication for your many sites with cloud saved passwords. For better security, ensure you spit security clearances for each factor. You can achieve this by using two separate accounts with unique credentials or cross-company with unique credentials. Always, unique credentials for each site kids, including usernames when crossing companies for your authentication needs. That’s 2 companies, 2 usernames/password, 2 factors totaling 6 unique values and is a good start!
In other words, what good is using a 2-key vault, if the bank manager is allowed to carry both keys at the same time?
This app is great
So a few months ago I got my Xbox account hacked and I was really sad about it because I had lost a lot. Including my games ect. But then I found out the hacker stole my email and put it in this app because at the time I didn’t have this app. So that was a good lesson for me to use this app always and it’s absolutely fantastic because I have a lot of emails like work, school, and gaming of course but I feel like all my emails are super secure also I like the fact that when trying to log into another site with your email you have to get permission from the Authenticator app before you can do anything so if someone gets ahold of your email then they can’t log in at all.
Convenience without compromising security
Microsoft Authenticator is the best MFA app. Since I use my Microsoft account all the time, having a second factor in authenticating gives me assurance & security. And the way it’s implemented is perfect—it sends me a notification, I select a number that matches with the browser, and scan my fingerprint (Touch ID). Amazing! And I can also add 2FA codes of other apps/sites such as Google & Facebook. The app also has iCloud backup & app lock with a passcode & biometrics.
