Beyond the Password: adding an Extra Layer
Even the strongest password can be stolen if a website's database is leaked. This is where Two-Factor Authentication (2FA) comes in. It adds a second lock to your door.
How 2FA Works
With 2FA enabled, logging in requires two things:
- Something you know (Your Password).
- Something you have (Your Phone or Email).
So, even if a hacker steals your password, they cannot access your account because they don't have your phone to get the OTP (One Time Password).
Types of 2FA
- SMS Codes: You receive a code via text message. (Good, but susceptible to SIM swapping).
- Authenticator Apps: Apps like Google Authenticator generate a new code every 30 seconds. (More secure).
- Hardware Keys: A physical USB key (like YubiKey) needed to log in. (Most secure).
We highly recommend enabling 2FA on your Email, Social Media, and Banking apps immediately.
