Password Generator

Create a strong random password with a length from 4 to 256 characters. Choose uppercase and lowercase letters, numbers, and symbols, and optionally exclude look-alike characters. Generation uses a cryptographically secure random source in your browser; generated passwords are not sent to our server. Strength and entropy are estimates, not guarantees.

Quick guide

How to use

Choose a length from 4 to 256, select character types, optionally exclude look-alike characters, review the estimates, generate or copy the password, and save it in a password manager.

About this tool

Customize your password

Choose 4–256 characters. Include uppercase letters, lowercase letters, numbers, and symbols to match account rules. Excluding look-alike characters such as 0, O, 1, l, and I may make a password easier to read, but reduces the available character pool.

Local generation and security

Passwords are generated in your browser with a cryptographically secure random number generator and are not sent to our server. Local generation does not guarantee complete security: your device, browser, extensions, clipboard, storage, and account protections still matter.

Strength and entropy estimates

The displayed strength label and entropy are indicators based on the selected length and character pool. They do not guarantee resistance to every attack. Favor long, unique passwords, save them in a reputable password manager, and enable multifactor authentication when available.
