Multifactor Authentication

Multifactor Authentication, or "two factor authentication" (2FA), is another layer of protection that comes after your password.

Examples include:

• temporary codes
• codes sent via email, SMS, or phone call
• "push notifications" sent to a separate application

All the time! If it is an option, you should use it. 

MFA can keep your data and money safe in case your password or device is stolen.

For accounts that do not have MFA built-in, you can sometimes use a separate "authenticator" application.

Examples include:

• the Oracle Authenticator app
• the Microsoft Authenticator app
• Google Authentication, which sometimes uses your other apps, e.g. YouTube, to confirm it's really you
• the Authenticator App
• the Okta app
