Read on to learn how 2FA protects your accounts.
TL;DR
Two-factor authentication, or 2FA, is a security method that adds an extra step to the login process. Instead of just entering a password, you provide two different types of proof to confirm your identity.
This makes it much harder for hackers to break into your accounts, even if they know your password.
How Does 2FA Work?
When you log in, 2FA asks for two things:
- Something you know: Usually, your password.
- Something you have or are: Like a code sent to your phone, a fingerprint scan, or a hardware key.
This second factor ensures you are trying to access the account.
Types
- SMS codes: You get a text with a code to enter.
- Authenticator apps: Apps like Google Authenticator generate temporary codes.
- Biometrics: Fingerprints or face scans.
- Hardware tokens: Physical devices that create or store codes.
Why Use 2FA?
There are multiple ways to crack a password, leading to it being stolen or guessed. Adding another layer, i.e., two-step verification, acts as a security system to shun unauthorized access.
Even if the password has been compromised, accessing the second-level authentication is hard.
Is Two-Factor Authentication Perfect?
There is no form of provided security that is 100% guaranteed. Adding steps such as using SMS for initial two-step verification makes accounts vulnerable to threats like SIM swapping attacks.
Using devices such as auth tokens or hardware paired with verification apps provides more security.
Final Thought
Regardless of one’s age, 2FA should be enabled in all accounts. It is a simple and effective method of bolstering the number of safeguarded online accounts from being hacked.
In essence, the concept of Two-Factor Authentication subscribes to two simplified beliefs: step down the path of enlightenment and bolster account security.
