Bulk Password Generator
Generate a whole batch of strong, random passwords at once and export them as TXT, CSV, or JSON — built entirely in your browser, so nothing is ever uploaded.
All 10 passwords are generated locally with crypto.getRandomValues(). Nothing is uploaded; the export files are built in your browser.
Generating passwords one at a time is fine for a single account, but provisioning a fleet of user accounts, seeding a test database, or rotating a batch of service credentials calls for a list. This tool produces as many strong, fully random passwords as you need — each an independent draw from your browser’s cryptographic random number generator — and lets you copy them all or download them in the format your workflow expects.
Every password is built locally with crypto.getRandomValues(); no list is ever sent to a server, logged, or stored. The TXT, CSV, and JSON files are assembled in your browser and saved straight to your device. Because the export is plain text, treat it like any other secret: import it into a password manager or store it in an encrypted location, and delete stray plain-text copies once you are done.
Frequently Asked Questions
How many passwords can I generate at once?
Up to 100 at a time here, each one an independent random draw. Change the count and the whole batch regenerates instantly. For a very large list, generate several batches and combine the exported files.
Can I export the passwords?
Yes. Download the batch as a plain-text (.txt), CSV (.csv), or JSON (.json) file, or copy them all to your clipboard at once. The files are assembled in your browser — nothing is sent to a server.
Is bulk password generation safe?
With this tool, yes: every password is created locally with your browser’s crypto.getRandomValues() and is never transmitted or stored. Be careful with the exported file afterward — keep it in a password manager or an encrypted location, and delete any plain-text copy once it has been imported.
Who needs to generate passwords in bulk?
System administrators provisioning many accounts, developers seeding test data or environment secrets, and anyone setting up users or devices at scale. A bulk generator removes the tedium of creating each password by hand while guaranteeing every one is strong and unique.
Are the generated passwords unique?
Each is an independent random draw, so duplicates are astronomically unlikely at any realistic length. At 16 characters with a full character set, the chance of two matching within a batch is effectively zero.
