How it works

Complete the job in three clear steps

Add an ID type, batch size, and Nano ID length to the private browser workspace.
Choose the available settings and create random identifiers.
Review the result, then copy or download it before leaving the page.

Important

Check the result before relying on it

Use these utilities for development, learning, and local checks. Do not treat a browser tool as a replacement for audited identity systems, password managers, production key management, or server-side authentication controls.

Practical details

What this Lucaden tool does

UUID values use the browser's cryptographically secure random UUID implementation, while compact identifiers use Nano ID's secure generator. Batch output is newline-separated for easy use in fixtures, spreadsheets, and test data.

Lucaden performs this task in the browser so the source stays under your control. The result is created only after you request it, and nothing is saved to a Lucaden account by this tool.

Questions

About this tool

Are generated IDs guaranteed unique?

No finite random identifier has an absolute guarantee, but UUID v4 and adequately sized Nano IDs have extremely low collision probability.

Can I use these as passwords?

Use the dedicated password generator, which makes character-set and length choices explicit.
