Two-factor mobile authentication
You can enable additional security for your Microsoft products using your Android device. It provides an alternative to email sign-ins with multiple account support.
Time-based, one-time pin
Microsoft Authenticator provides extra security for your Microsoft accounts with a two-factor verification process. It creates a random six-digit code, which changes every thirty seconds. You can also use it with non-Microsoft accounts, but you'll need to log into your account to set it up.
There are other apps that support extra platforms with a better user interface, such as Authy's authenticator app. However, Microsoft Authenticator has additional security protocols in place, ensuring that hackers can't steal your codes. The security options include approval via the app or sending the code by SMS, email, or phone call.
Certification for organisational approval
Some companies and schools require you to use the app to access particular files and emails. In these cases, you'll log in to the organisation's account through the app. It reassures the company that you're reading the files from a trusted device.
To ensure the maximum security for your accounts, you'll receive push notifications on your Android smartphone to approve access. You'll always be aware of login attempts, even if someone else is trying to enter your accounts.
Free authenticator with no adverts
It's a common feature for adverts to appear in free applications. Yet, Microsoft Authenticator is a free app with no advertisements. You can enjoy all its security features on your Android device without interruptions from unsolicited marketing.
Free two-step verification
Microsoft Authenticator is a safe application to use that doesn't require a QR code, unlike the Google Authenticator app. It's specifically designed to add security for Microsoft accounts, but also provides functionality for other accounts such as Facebook, Quickbooks, and Twitter. What it lacks in the user interface, it makes up for with additional security protocols.
