Password Generator

Create strong, random passwords with configurable length and character sets.

Create strong, random passwords with configurable length and character sets.

Quick start: Set the password length, longer is stronger, with 16 or more recommended. → Choose which character sets to include: uppercase, lowercase, digits, and symbols. → Click Generate to produce a fresh random password.

Who is Password Generator for?

Anyone creating a strong, unique password for a new account

Security-conscious users rotating old or reused passwords

IT admins provisioning temporary credentials for new staff

Developers generating initial secrets and API keys

Why use Password Generator?

  • Uses the browser's Web Crypto API (crypto.getRandomValues) for cryptographically secure randomness, not Math.random.
  • Lets you tune length and which character sets are included to match each site's rules.
  • Longer lengths add real entropy, making brute-force attacks exponentially harder.
  • One-click copy gets the password straight into your password manager.
  • Generated passwords never leave your device, so they are safe to create even on a shared machine within one session.

Common use cases

  • Create a strong, unique password for a brand-new account.
  • Rotate an old or reused password to a fresh random one.
  • Provision a temporary credential for a new employee or contractor.
  • Generate an initial secret or API key for a database or service.

How Password Generator keeps your data private

Passwords are generated using the browser's Web Crypto API (crypto.getRandomValues), which uses cryptographically secure entropy from your operating system. Critically, generated passwords never leave your device — not to our servers, not to analytics, not to logs. You can generate a password with confidence even on a public machine, knowing nothing persists after the tab closes.

ToolMain limitation
LastPass generatorPushes you toward a LastPass account and ties output to their vault
1Password generatorBundled inside a paid 1Password subscription
Random.org password toolGenerates server-side, so passwords pass through their infrastructure
Password GeneratorFree, runs in your browser, no sign-up, no watermarks, no file-size limits beyond your device memory.

Limitations & things to know

  • Cannot enforce a specific site's exact composition rules, you choose the character sets yourself
  • Does not store passwords, so you must save each one in a password manager before closing the tab

About Password Generator

A password generator creates random passwords that are far harder to guess or brute-force than anything a human invents. Xevon Tools' Password Generator builds each one in your browser using the Web Crypto API, specifically crypto.getRandomValues, which pulls from your operating system's cryptographically secure random source. That detail matters more than it sounds: many weak tools use JavaScript's Math.random, which is a predictable pseudo-random generator never intended for security and theoretically reversible by an attacker who sees enough output. This tool avoids that entirely. You control the length and which character sets are mixed in, uppercase letters, lowercase letters, digits, and symbols, so you can satisfy a site's specific composition rules. The single most important setting is length. Password strength is measured in entropy, and every additional character multiplies the total number of possibilities, so a 20-character password drawn from letters and digits is dramatically harder to crack than a 10-character one stuffed with symbols. Add symbols when a site demands them, but do not trade away length to fit a short maximum. The other rule that makes generation worthwhile is uniqueness: generate a different password for every account and store each in a password manager, so that a breach at one service cannot be replayed against your others. Use the tool to create new-account credentials, rotate reused passwords, provision temporary access for a new hire, or seed an initial API key. Because nothing is transmitted, logged, or saved, you can generate safely, and once the tab closes the password is gone unless you have stored it yourself.

Frequently asked questions

Yes. It uses crypto.getRandomValues from the Web Crypto API, which draws from the operating system's cryptographically secure entropy source. This is fundamentally stronger than Math.random, which is predictable and must never be used for passwords.
Length is usually the bigger win. Each extra character multiplies the number of possible passwords, so a long all-letter password can be far harder to crack than a short one peppered with symbols. Add symbols too where a site requires them, but do not sacrifice length to fit a short cap.
No. Generation happens entirely in your browser and nothing is transmitted, logged, or saved. Once you close the tab, the password is gone unless you saved it yourself.
Never. The whole point of a generator is a unique password per account, so that a breach at one site cannot unlock the others. Store each one in a password manager.
