What Is Two-Factor Authentication (2FA)? | Microsoft Security (2024)

Implementing 2FA within a business or personal setting is beneficial in protecting vulnerable networks and databases.

With a mobile device, you can generate your own codes, or tokens, to provide a unique set of letters/numbers to verify your identity. These codes are sent via SMS and are verified through a website or app. It is important to note that the website or app that you’re identifying yourself through is reliable and safe.

One-time passcodes that are generated through apps or websites are more time-sensitive than an SMS code or token.

Here are some tips to ensure your two-factor authentication implementation goes as smoothly as possible.

• Consider using the most common method of implementation, SMS authentication. It’s convenient and ensures that all user identities are verified via a reliable phone number.
• Remember that most users can implement 2FA through the security settings of their smartphone or electronic device.
• Find the right two-factor authentication provider. Each company that hosts authentication services has their own process of implementation. For example, theAuthenticator appallows you to register one or more of your business/personal devices to ensure that all are protected.

Businesses and individuals can implement these two forms of 2FA through Microsoft’sAuthenticator app. This service provides authenticator options, both two-factor and multi-factor, depending on your unique individual or business needs.
