We use them at home for our personal devices and accounts, and we especially use them at work. This is why locking down your login by using two-factor authentication whenever possible is one of the strongest steps we can take to protect our accounts. Two-factor authentication is an extra form of security for our account logins or devices.
Two-factor authentication works in the following way:
- Enter your password.
- You'll be asked for something else to be authenticated before you continue, such as a code sent to your phone, voice call, or mobile application verification.
Examples of two-factor authentication:
- Mobile device
- Allows for a code to be sent as a text message or voice call
- Mobile devices also allow for applications such as Google Authenticator, LastPass Authenticator, or Microsoft Authenticator.
- Security token/key card
- Hardware device which can be used to authenticate with your account which contain a randomized code.
- USB device
- Devices such Google's Titan Security Key and Yubico's YubiKey are two-factor USB devices. Once the device is enabled, they work by simply entering the USB to the computer and then pressing a button on the device to authenticate.
