Two-Factor Authentication (2FA) is the use of two of the following three identification factors:
- Something you know – Most often a password for your account.
- Something you have – Such as a cell phone with a temporary authentication code.
- Something you are – Such as your fingerprint or facial recognition.
Using two of these three identification factors is the best way to protect your critical accounts. Hackers know that most people don’t have or use password managers set up with strong passwords and they don’t use 2FA. As a result these hackers send out phishing attacks to steal unsuspecting user’s login credentials. With two-factor authentication enabled on your accounts, it will require more than just your username and password to gain access to those accounts. Hackers would also require another identification factor (something you have or something you are), effectively locking hackers out of your accounts.
Start enabling 2FA on your critical accounts. Your bank probably requires 2FA already for online backing. Use it there and also enable on critical accounts like your Email, company VPN, and any Internet facing services you provide to your clients.
