Bulk Password Generator

Used by developers, writers, and creators worldwide.

A bulk password generator solves a specific bottleneck: you need dozens of strong, unique passwords right now, not one at a time. Sysadmins use it when onboarding new employees, developers use it to seed staging databases, and security teams use it to populate test fixtures. Set the count (up to 10 by default, adjustable per batch), dial in the length, and toggle uppercase letters, numbers, and symbols to match whatever your target system requires. Every password is generated locally in your browser. Nothing is transmitted, stored, or logged. If a legacy system rejects symbols, disable that toggle before generating and avoid editing 50 passwords by hand afterward.

How to use

  1. Choose your options above
  2. Click Generate
  3. Copy your result

Detailed instructions

  1. Set the Count field to the number of passwords you need, up to 100 per batch.
  2. Adjust the Length field to match the minimum or maximum required by your target platform.
  3. Toggle Uppercase, Numbers, and Symbols on or off to meet the platform's character rules.
  4. Click Generate to instantly produce the full list of passwords in the output panel.
  5. Copy the entire list and paste it into your password manager, CSV template, or provisioning script.

Use Cases

  • •Provisioning credentials for 20+ new employee accounts during bulk onboarding
  • •Seeding a Postgres staging database with realistic password fixtures for integration tests
  • •Generating temporary default passwords for a bulk user-import CSV in a SaaS platform
  • •Creating varied credential sets for penetration testing scenarios in Burp Suite
  • •Populating a Jest or Cypress test suite with unique per-user password data

Tips

  • →For systems that reject symbols, disable only that toggle rather than shortening the password — length compensates for entropy loss.
  • →Generate a batch of 10 first to visually spot-check that the format meets requirements before running a full batch of 100.
  • →Pair the output with a spreadsheet: paste passwords into column B alongside usernames in column A for a ready-to-import CSV.
  • →If a platform has a maximum length limit, set Length exactly to that limit rather than below it to maximise password strength.
  • →Run two separate batches with different settings if you're provisioning two tiers of users with different permission levels and password policies.
  • →After generating, search the list for any accidentally produced offensive strings before distributing — rare but worth a quick scan.

FAQ

how secure are randomly generated passwords from a browser tool

Passwords are built by randomly sampling from your enabled character set using the browser's built-in JavaScript engine. At length 16 with uppercase, numbers, and symbols all on, there are over 10^28 possible combinations per password — brute-force attacks are computationally infeasible at that scale.

are the passwords sent to a server or stored anywhere

No. All generation runs entirely in your browser and nothing is transmitted or logged. You can disconnect from the internet before generating if you want extra assurance.

can I generate passwords that match specific platform rules like no symbols

Yes — toggle uppercase, numbers, and symbols independently before generating. If a system forbids symbols or requires a specific length, set those controls first so every password in the batch is already compliant and needs no manual editing.
