API Key Generator

Generate Random API Keys and Tokens

API keys and tokens need to be long, random, and unpredictable. Our API key generator creates cryptographically random strings using the Web Crypto API built into your browser — the same randomness source used for TLS encryption. The default 32-character alphanumeric format works with virtually any API or service. No symbols by default to avoid URL-encoding issues. Everything is generated client-side — your keys never touch a server. Need to share the key securely? Use the built-in share button to create an encrypted one-time link.
