Strong Password Generator
Generate cryptographically secure passwords using your browser's Web Crypto API. All generation happens locally — your passwords never leave your machine.
Uses Web Crypto API (crypto.getRandomValues) for cryptographically secure random number generation. The generated password is as secure as your browser's underlying entropy source. Aim for 16+ characters with all character sets enabled for maximum security.
What makes a password actually strong
Password strength comes from entropy, the number of possible combinations an attacker must try. Length contributes far more entropy than swapping letters for symbols, which is why a long random string beats a short clever one. For infrastructure work you generate credentials constantly: database passwords, service account secrets, API tokens and encryption keys. Each should be long, unique and random so a leak in one place never unlocks another.
Generate credentials without leaving your browser
This generator uses your browsers cryptographic random source and produces the value locally, so a fresh secret is never transmitted or logged. Adjust length and character sets to match a systems requirements, then copy it straight into your secrets manager. Because each value is unique, you avoid the biggest real-world risk, which is reusing one password across many systems where a single breach cascades.
Common credential mistakes and how to fix them
The top mistakes are reusing passwords, storing them in plaintext files or committing them to Git. Rotate high-value credentials regularly and keep them in a dedicated secrets manager or a Kubernetes Secret rather than in code. Never hardcode a token in a container image, where anyone who pulls the image can read it. For a broader hardening checklist covering secrets in clusters, see our Kubernetes security best practices guide.
Frequently asked questions
How long should a password be?
Aim for at least 16 characters for important accounts; longer random strings resist brute-force far better.
Are symbols more important than length?
No. Length adds more entropy than symbol substitution. A long random string is stronger than a short complex one.
Is this generator safe to use?
Yes. It runs entirely in your browser using the cryptographic random source and never sends the value anywhere.
Should I reuse a strong password?
Never. Reuse means one breach exposes every account. Generate a unique value per system.
