What is Multi-Factor Authentication? 🔐

We always choose the same password for all our online accounts.

We reuse our password on less reliable platforms - these are often hacked.

The consequence of these hacks is that all passwords end up on the Internet without your knowledge.

Passwords are not secure enough. A more secure solution is Multi-Factor Authentication.

Multi Factor Authentication(MFA) is a way in which authentication is granted using an additional factor. Or multiple factors -> Multi-Factor.
