Passwords & Security

An educational random word list for interface testing. The shortened dictionary and lack of a checksum mean the result is not a complete BIP39 seed phrase. Never use it in a real wallet.

Random 4-, 6- or 8-digit PINs for cards, devices and apps — cryptographically secure

Creates a random string from selected character groups in the browser. Character selection uses Web Crypto; the result is not added to this site's generation history.

Random API keys in Hex, Base64 or UUID format for web services and development

Passwords without similar characters 0/O/l/I/1 — easy to type, hard to crack

Creates UUID v4, UUID v7 and ULID. Random parts use Web Crypto. Version 1 is not supported; enforce uniqueness separately in your own system.

Random MD5, SHA-1, SHA-256 and SHA-512 hashes for testing and development
