Bulk Password Generator

Summary

Generate up to 100 unique passwords at once with configurable length and character sets.

How it works

1. Set the password length (8–64) and how many passwords you need (up to 100).
2. Choose which character sets to include: uppercase, lowercase, numbers, and symbols.
3. The browser's crypto.getRandomValues() API builds a character pool and draws cryptographically secure random characters for each password.
4. A uniqueness check removes duplicates so every password in the batch is distinct.
5. Use Copy All to copy the full list, one password per line.

Use cases

• Provision temporary credentials for multiple new user accounts at once.
• Generate a set of strong passwords for testing authentication systems.
• Create one-time-use passwords for a group of test environments.
• Quickly seed a password manager with fresh, unique credentials.
