Strong, random passwords

The two things that make a password strong are length and genuine randomness, and human-invented passwords reliably fail at both. This generator draws from your browser's cryptographically secure random source rather than a predictable pseudo-random function, lets you set the length and which character sets to include, and shows a live strength indicator. The password is created on your device and never transmitted.

How to generate a strong password

  1. 1

    Set the length

    Longer is the single biggest win. Sixteen characters or more is a sensible floor.

  2. 2

    Choose character sets

    Include uppercase, lowercase, numbers, and symbols — or drop symbols when a system will not accept them.

  3. 3

    Copy it into your password manager

    Generate, copy, and save it straight away. A random password you cannot remember is only useful if it is stored somewhere.

Good to know

  • Randomness comes from the Web Crypto API, the same secure source your browser uses for encryption, not from `Math.random()`.
  • Nothing is generated on a server, logged, or transmitted — the password exists only in your browser tab.
  • Length beats complexity: a long password with fewer character types is generally stronger than a short one full of symbols.
  • Use a different password everywhere and let a password manager remember them; reuse is what turns one breach into many.

What people use it for

  • Creating a unique password for a new account instead of reusing an old one
  • Generating a strong value for a database user, API secret, or service account
  • Replacing a password after a service you use has been breached

Frequently asked questions

Are these passwords truly random?+

Yes. They are generated with `crypto.getRandomValues`, your browser's cryptographically secure random source rather than Math.random.

What does the strength meter mean?+

It estimates entropy in bits based on length and the character sets you enable. More bits means harder to crack; aim for 70+ bits.

Is my data sent to a server?+

No. Generating passwords happens entirely in your browser using built-in web APIs. Nothing is uploaded, stored, or logged.
