Quick answer

Password is a free, private online tool that lets you generate strong, random passwords with custom length and character sets. It runs entirely in your browser, so nothing you enter is uploaded to a server.

How to use the Password

  1. Set the options (such as length, amount or character types) to suit your needs.
  2. Click Generate to produce a fresh result — generate again for new values.
  3. Click Copy to copy the output to your clipboard.
  4. Everything is generated locally in your browser, so nothing is sent anywhere.

Privacy: this tool runs entirely in your browser. Your input is never sent to, received by, or stored on any server — there are no uploads and no tracking of what you enter.

About Password

What makes a strong password

Length and randomness matter most. A long password drawn from a large character set is far harder to crack than a short complex one.

Cryptographic randomness

Passwords are generated with the browser's crypto.getRandomValues, so they are unpredictable — unlike Math.random based tools.

Privacy

Generation happens entirely in your browser; passwords are never sent anywhere. Still, use a password manager to store them.

Frequently asked questions

Are these passwords secure?
Yes — they use cryptographically secure randomness and never leave your device.
How long should a password be?
At least 12-16 characters; longer is better, especially for important accounts.
Should I reuse passwords?
Never. Use a unique password per site, stored in a password manager.

Understanding Password in depth

What makes a password strong

Password strength comes mainly from length and randomness, not from clever character substitutions. A long password drawn from a large pool of characters has astronomically more possible combinations, which is what defeats brute-force guessing. This generator builds genuinely random passwords from the character sets you choose, at the length you set.

Why randomness matters

Human-chosen passwords follow predictable patterns - names, dates, keyboard runs, common words with a number on the end - and attackers exploit exactly those patterns. A password generated from cryptographically secure randomness has no such structure, so it cannot be guessed by dictionary or pattern-based attacks. This tool uses the browser's secure random source, not the weak, predictable Math.random.

Length versus complexity

Adding length increases strength far faster than adding symbols. Each extra character multiplies the number of possibilities, so a long passphrase or a 16-plus character random string beats a short, fiendishly complex one. Aim for at least 12 to 16 characters; use more for important accounts like email and banking, which are the keys to everything else.

Why you should never reuse passwords

The biggest real-world risk is reuse. When one site is breached, attackers try the leaked email-and-password combination on hundreds of other sites - 'credential stuffing'. A unique random password per site means a breach of one account cannot unlock the others. A password manager makes this practical by remembering them all for you.

Privacy and how to use it

Set the length and tick the character types you want (uppercase, lowercase, digits, symbols), then generate one or many at once. Crucially, generation happens entirely in your browser - passwords are never sent anywhere - so they are safe to use. Store the result in a reputable password manager rather than reusing or writing it down insecurely.
