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.

Font size missing

As many people do, I have several email accounts. In my case most with the same name. The problem with Authenticator is the large font size. My accounts all appear as;
Is it or I can't tell because they are all cut off! A font size option is needed.

Watch app doesn’t work.

I have the latest update of the watch app running on WatchOS 5.0. I get prompted to authorize, but tapping approve does nothing. I still have to launch Authenticator on my phone and approve from there.

Useful if you don’t already use say Google Chrome

I mean, it works. It does what it’s supposed to do. But I have Google Chrome, and it saves passwords. I get into my email address in under 5 seconds with Chrome. It took a solid 15-20 seconds with this app.

You need to tap the authentication button first, then wait for the notification, then tap approve, then use your finger print sensor, then wait again for it to log you in.

With Chrome - you just tap (or click) your email, hit sign in, done.

Now if you don’t already use a browser that saves your passwords, then yes, this app could save you time, but again, only if you have a really long or confusing password, or you have a tendency to forget your passwords (such reason I save mine with Chrome).

But it works good, so if you need it, it’s great. It’s not to slow, but it’s not exceptionally fast either.
