MFA stands for Multi-Factor Authentication. It's a security process that requires you to prove your identity using more than one method. Normally, when you log into something, you just enter your password—that's one factor. MFA adds extra layers of protection by asking for at least one more factor.
These factors fall into three categories:
1. Something you know (like your password or a PIN).
2. Something you have (like your phone or a security token).
3. Something you are (like your fingerprint or face recognition).
For example, after entering your password (something you know), MFA might ask you to enter a code sent to your phone (something you have). Even if someone steals your password, they can't get in without the second factor.
MFA makes it much harder for hackers to break into your accounts, providing a stronger defense against unauthorized access.
