Tool Introduction

Generate cryptographically secure random tokens for API keys, session secrets, coupons and test data. Pick a character set, set the length, and produce up to 1,000 tokens in a single click - as plain strings, hyphenated groups, or version-4 UUIDs.

Every token is created locally with the Web Crypto API (crypto.getRandomValues), so nothing is ever sent to a server. Toggle unique-only output to avoid duplicates and exclude ambiguous characters such as 0, O, 1, l and I when you expect tokens to be typed by hand.
