Enabling two-factor authentication (2FA) is the single most important thing you can do to improve the security of your online accounts.
What is 2FA?
Two-factor authentication (2FA) is a way of strengthening the login security of your online accounts. It’s similar to how an ATM works. You need both your debit card (first factor) and your PIN (second factor) to get access to your account and withdraw cash. The main objective is better security. If your card is stolen, they still need your PIN. If your PIN is stolen, they still need your card.
Enabling 2FA will help to stop hackers from getting into your accounts, even if they have your password.
