Password Generator

Create strong, truly random passwords using a cryptographic source — free, nothing stored.

100% free No signup No watermark Processed in memory, never stored

How it works

  1. Set length. Choose a length (16+ is a good baseline) and how many passwords to create.
  2. Choose character types. Tick lowercase, uppercase, digits and symbols to match the site’s rules.
  3. Generate. Press Generate and copy any password — they are made with a cryptographic random source.

About this tool

Generate strong, random passwords with the character types you choose — lowercase, uppercase, digits and symbols — at any length from 4 to 128. Every password is produced with Python's cryptographic secrets module, which is designed for security rather than the predictable output of a normal random function. You can create up to 50 at once, which is handy when setting up several accounts. Nothing is logged or stored — the passwords exist only on the page you're looking at.

What people use it for

  • Make a unique password for a new account
  • Generate a batch of logins for a team or family
  • Create a strong Wi-Fi or router password
  • Replace a weak reused password with a random one

Developer API

Automate this tool from your own code. Send a POST request to the endpoint below and get the same result the web tool produces. It is rate-limited per IP and needs no signup — API keys for higher limits are coming.

Frequently asked questions

They use Python’s secrets module, a cryptographically secure random source built for tokens and passwords — not the predictable pseudo-random generator used for ordinary code.

Any length from 4 to 128 characters, with lowercase, uppercase, digits and symbols each toggled on or off to match a site’s rules.

Yes — up to 50 in a single run, which is useful when creating multiple accounts at the same time.

No. They are generated for your request and never logged, stored or transmitted onward — they only appear on your screen.

No signup and no payment. It is free with a fair hourly limit per IP.

Sixteen characters or more is a sensible baseline; go longer for important accounts. Including symbols and digits increases strength further.

To avoid producing an unusable password, the tool falls back to a safe mix of letters and digits.

Yes. POST a JSON body to /api/tools/password-generator/ and you get a JSON response back — the same engine the web tool uses, so results are identical. It is rate-limited per IP like the web version and needs no signup; API keys for higher limits are coming. See the API section above for ready-to-run curl, Python and JavaScript examples.
