What is Password Generator?

Generate random passwords locally with configurable length and quantity.

  • Generate random passwords locally
  • Set length and output quantity
  • Use a fixed, unambiguous character alphabet

How to use it

  1. Enter password length on line 1 and the number of passwords on line 2.
  2. Use a length accepted by the destination service; the page supports 6 to 128 characters.
  3. Generate and choose a different value for every account.
  4. Store the selected password in a trusted password manager instead of chat, notes, or source code.

Quick example

Example input

20
3

Expected output

Three random 20-character passwords

The generator uses browser Web Crypto random values. For single-factor use, current NIST guidance requires at least 15 characters; always follow the destination service's rules.

Best use cases

  • Create unique passwords for new accounts.
  • Generate temporary test credentials without reusing personal passwords.
  • Prepare long random values for password-manager storage.

Reference standards and behavior

NIST guidance emphasizes password length, blocklists, secure handling, and rate limiting. This page only generates random strings and cannot evaluate a service's full authentication controls.

Sources checked July 24, 2026. Standards can change; review the source pages before formal integration.

Notes

  • The character set avoids several easily confused characters.
  • The page does not save generated passwords, so store the chosen value before closing it.
  • Do not reuse a generated password across services.

FAQ

Are generated passwords stored?

No. Generation runs in your browser, and DataHub does not receive or store the results.

How many passwords can I generate at once?

Enter a quantity from 1 to 50 on line 2. Values outside that range are limited to the nearest supported value.

Which password lengths are supported?

Enter a length from 6 to 128 characters on line 1. Values outside that range are limited to 6 or 128.

Which characters can appear?

The generator uses a fixed alphabet of upper- and lowercase letters, digits 2-9, and common symbols. Several easily confused characters are omitted.

How are random values generated?

The page uses the browser Web Crypto getRandomValues API instead of Math.random.

Does the generator work on mobile?

Yes, in a modern browser that supports Web Crypto. Store the chosen password safely before closing the page.

Does every supported length count as a strong password?

No. The 6-character minimum supports compatibility and testing. Current NIST guidance requires at least 15 characters for single-factor passwords and at least 8 when used within multi-factor authentication.

Is generating a password enough to secure an account?

No. Use a trusted password manager, avoid password reuse, and enable multi-factor authentication where available.
