A password is only one layer of protection. If someone steals it, they can access your private conversations and your identity. Two-Factor Authentication (2FA) is a second, different lock for your accounts.
Why One Key Isn't Enough
Think of your online security like a high-security vault. Your password is the first door. In a world of data breaches and sophisticated phishing, that first door is often easier to pick than we’d like to admit. 2FA acts as a second vault door—one that requires a completely different kind of key that only you possess.
Even if an attacker discovers your password through a leak or a trick, they remain locked out because they cannot provide the second piece of evidence required to prove your identity.
Why One Key Isn't Enough
SMS Text Codes
Problem: Codes can be intercepted through "SIM swapping" or local network surveillance. It is the weakest form of 2FA.
Best Use: Use only if no other 2FA option is available. Better than having no 2FA at all.
Authenticator Apps
Benefit: Generates codes locally on your phone. Works offline and is much harder to intercept than SMS.
Best Use: Ente Auth or Google Authenticator.
Hardware Keys
Benefit: A physical USB or NFC key. It is virtually impossible to phish because the key must be physically present.
Best Use: YubiKey. Recommended for high-risk individuals, activists, and journalists.
