Microsoft recently released a new version of the Azure Authenticator that replaces the Multi-Factor Authentication app published by PhoneFactor. Azure Authenticator can be the single application you need for all your multi-factor authentication needs. It not only works for accounts protected by Azure Multi-Factor Authentication but also works with Microsoft account, Google and any other provider that supports OATH one-time passcodes.
Azure Authenticator allows you to secure your accounts with two-step verification. With two-step verification, you sign in using something you know (your password) and something you have (your mobile device).
When used with an account protected by Azure Multi-Factor Authentication, a push notification is sent to your mobile device to alert you of a pending two-factor verification request. Simply tap on the notification to launch the app and tap Verify to complete the verification. Alternatively, you may be prompted to enter the verification code displayed in the app. The app supports Azure Multi-Factor Authentication and other software tokens such as those used with Microsoft and Google accounts.
