The Problem with Password Reuse

When you reuse a password, a single breach compromises *all* your accounts. Attackers use a technique called **credential stuffing** -they take leaked username/password pairs from one breach and try them on every major site.

// Example: How credential stuffing works
const breached_credentials = [
    {"email": "user@ficita.test", "password": "password123"},
    // ... millions more from a data breach
]

for (const site of ["google.com", "github.com", "bank.com"]) {
    for (const cred of breached_credentials) {
        try_login(site, cred.email, cred.password)
        // If it works, the account is compromised!
    }
}

Two-Factor Authentication (2FA)

2FA adds a second layer of security beyond your password. Even if your password is compromised, an attacker can't access your account without the second factor.

Password Managers

A password manager is the single most impactful security tool you can adopt. It generates, stores, and auto-fills unique passwords for every site, so you only need to remember one master password.
