Generate Strong, Human-Proof Passwords

Tailor password policies for teams or personal vaults, copy multiple credentials at once, and understand the strength score before you save.

Character sets

Overview

Reusable passwords remain one of the biggest attack vectors for individuals and businesses. Our generator removes guesswork by producing high-entropy strings with the exact character mix your policy requires.

It relies on the browser’s Web Crypto API, so secrets never touch a server. You can generate batches of unique passwords, avoid look-alike characters, and export them to your password manager in seconds.

Key features

  • Adjustable length & batch size

    Use sliders and dropdowns to generate up to ten passwords at once with lengths between 8 and 64 characters.

  • Fine-grained character controls

    Toggle lowercase, uppercase, numbers, symbols, repetition rules, and specific characters to exclude based on vendor requirements.

  • Entropy guidance

    See estimated bits of entropy and an at-a-glance strength label for every generated password to align with NIST and OWASP recommendations.

  • Copy individually or in bulk

    Copy a single password with one click or export the entire list for quick onboarding of service accounts and shared vaults.

How it works

  1. 1

    Set policy parameters

    Adjust the length slider, choose how many passwords you need, and enable the character classes allowed by your security policy.

  2. 2

    Refine exclusions

    Avoid ambiguous characters like O and 0 or remove characters that conflict with specific systems using the exclusion field.

  3. 3

    Generate secure strings

    Click “Generate” to produce cryptographically random passwords. Review entropy and tweak settings if the strength label is below your target.

  4. 4

    Copy & store safely

    Copy results into your password manager or share via encrypted channels. Use the copy-all action when onboarding multiple accounts.

Use cases

Onboard new team members

Generate a set of unique credentials for dev, staging, and analytics tools before inviting a teammate to a shared vault.

Harden IoT or admin panels

Replace manufacturer-default passwords with high-entropy strings that still respect firmware character limitations.

Create throwaway campaign logins

Build time-limited credentials for temporary projects and rotate them easily once the work wraps up.

Examples & tips

Generate 12 random passwords for staging

Set length to 24, keep all character sets enabled, and copy-all to paste into your password manager for distribution.

Exclude confusing characters for support agents

Enable avoid-similar and exclude O, 0, l, and 1 to provide readable yet secure passwords for phone-based resets.

Meet strict vendor rules

Disable symbols, enable no-repeat, and ensure entropy still clears 80 bits before saving credentials for legacy systems.

Pro tips

  • Rotate passwords regularly and enable multi-factor authentication whenever possible.
  • Use the Data Converter to create CSV imports for enterprise password managers.

Frequently asked questions

Are passwords generated locally?
Yes. The tool uses window.crypto.getRandomValues so generated strings never leave your device.
What entropy value should I target?
Aim for at least 80 bits for individual logins and 100+ bits for privileged or shared accounts.
Can I save templates for later?
Bookmark the tool with query parameters coming soon. For now, settings persist during your session so you can generate batches quickly.
Does the generator store my passwords?
No storage takes place. Clear the page or close the tab to discard generated results.
