API Key Generator
Generate secure, random passwords with custom options. Free, fast, and runs 100% in your browser.
API keys and secret tokens require high entropy to prevent unauthorized access. This generator creates cryptographically random strings using the Web Crypto API — the same standard used by security-critical infrastructure. Generate keys of any length with full control over character sets.

Frequently Asked Questions
How long should an API key be?
32-64 characters is standard for API keys. Longer keys provide exponentially more security against brute-force attacks.
Are these keys truly random?
Yes. They use crypto.getRandomValues(), a CSPRNG — far more random than Math.random() or timestamp-based generation.
