About the Password Generator
A strong password is your first line of defense against unauthorized access. This generator uses your browser's cryptographically secure random number API (crypto.getRandomValues) — the same standard used by security software — so every password is genuinely unpredictable.
How it works
Charset = uppercase + lowercase + numbers + symbols
Entropy = length × log₂(charset size)
Example = 16 chars × 94 symbols → ~104 bits of entropy
104 bits of entropy would take billions of years to brute-force on the fastest hardware today.
What makes a password strong
- 📏Length matters most. Going from 12 to 16 characters adds exponentially more combinations.
- 🔣Including symbols and numbers expands the character pool, making each position harder to guess.
- 🚫Never reuse passwords. A breach at one site exposes all accounts that share the same password.
- 🔑The hardest part isn't generating a strong password — it's remembering one per site. That's what password managers are for.
