What is Two-Factor Authentication?
Two-Factor Authentication, or 2fa, is an extra layer of protection used to ensure the security of online accounts beyond just a username and password. By requiring two different channels of authentication, we can protect user logins from remote attacks that may exploit stolen usernames and passwords. The factors may include: something you know (unique username and password) and something you have (smartphone with an app to approve authentication requests).
At Butler, two-factor authentication is required in addition to password in order to log in to most systems.
Why Do We Need Two-Factor Authentication?
Over 90% of breaches today involve compromised usernames and passwords. Two-factor authentication enhances the security of your account by using a secondary device (such as your smartphone) to verify your identity. This prevents anyone but you from accessing your account, even if they know your password.
