About this tool
Need a random code for your project, app, or everyday task? The Random Code Generator on FirstRandom gives you a collection of specialized tools designed to produce codes of any type - from secure passwords to unique identifiers.
What You Can Generate
This category brings together a range of specialized generators, each built for a specific kind of code. Create UUIDs in versions from v1 to v8, generate strong passwords with full control over length and character sets, or produce cryptographic tokens in HEX, Base64, and URL-safe formats. Need something simpler? Generate random PINs with custom digit length, promo codes in popular templates like XXXX-XXXX, or complete random credentials for testing environments.
Who Benefits from Random Codes
Developers use random code generators daily - for database seeding, API testing, and building authentication flows. QA engineers rely on random credentials and tokens to stress-test applications. Marketers generate batches of unique promo codes for campaigns. And anyone who values online security can create strong, random passwords in seconds instead of reusing the same one everywhere. Each tool lets you generate up to 50 codes at once, so whether you need a single UUID or a batch of promotional codes, you get results instantly.
Fast, Flexible, Free
All generators work right in your browser with no registration required. Pick your code type, adjust the settings, and hit generate. It is that straightforward.
