What Makes a Password Truly Strong?
Length, randomness, character variety, and uniqueness. Our free Password Generator uses crypto.getRandomValues() — the same cryptographic API used by banks — to generate passwords that are impossible to guess.
Password Length Guide
- 8 characters — Crackable in minutes. Never use this.
- 12 characters — Takes years. Minimum for most accounts.
- 16 characters — Recommended standard. Effectively uncrackable today.
- 20+ characters — Use for email, banking, and password manager master password.
Why Random Beats Memorable
Humans create patterns — names, dates, keyboard walks. Attackers target these first. A cryptographically random password like Kx9#mP2$nQ7@vL4! has no pattern.
Security Checklist
- Never reuse passwords across different sites
- Enable two-factor authentication (2FA) on all accounts
- Use a password manager to store all passwords securely
