What is a secure password generator?
A secure password generator creates random passwords using the browser cryptographic generator (crypto.getRandomValues), with configurable length and character types. Everything happens locally: no password is sent to a server or stored.
How to use this tool
- Adjust the password length with the slider (from 4 to 128 characters).
- Tick the character types you want to include.
- Choose how many passwords to generate at once if you need several.
- Press "Generate" and check the strength indicator.
- Copy the password and store it in your password manager.
Typical use cases
- Create unique passwords for each online account.
- Generate keys for projects, API keys or workspace credentials.
- Rotate passwords periodically while keeping high entropy.
Frequently asked questions
How secure are these passwords?
They use the browser cryptographic generator, the same randomness source used by TLS protocols. A 16-character password with all four character types offers more than 100 bits of entropy.
Why should I exclude ambiguous characters?
Characters like 0, O, l and 1 are easy to confuse when typing them by hand. Excluding them prevents errors when entering the password on devices without a password manager.
Is the password sent to any server?
No. Generation is 100% local in your browser and the password only exists on your screen until you copy it.
