Two-factor authentication (2FA) explained: A powerful defense against hackers 🧙♂️
Two-factor authentication, also known as 2FA, is a security mechanism that requires users to provide a second form of authentication in addition to their password before accessing their accounts. This second factor can take various forms, such as a one-time authentication code via text message, a push notification to a mobile app or biometric identification such as fingerprint or facial recognition. Using 2FA makes it significantly more difficult for hackers to gain access to your account, even if they have obtained your password.
