Two-factor authentication, or two-step authentication, is a login process where the user is asked to provide two authentication points, such as a password and a code shared through a text message. Two-factor authentication enhances login security.
I think a Two-Factor Authentication is very important because hackers can easily get through usernames and passwords but having a specific code sent to your email or phone number is something only yo have access to. I like these because it personally makes me feel like my information is safe!
