Hunter's comment

It is an original app by Microsoft corporation.
Microsoft Authenticator supports multi factors authentication (MFA) even if you still use a password, by providing a second layer of security after you type your password .
You can also add multiple accounts to your app including non Microsoft like Google, Facebook and more.
Now secure your accounts with Microsoft Authenticator.
