Strong Password Generator: Free Online Tool & Complete Guide

What is the Strong Password Generator?

Weak, reused passwords are the number one cause of account breaches. The best defense is a long, random password generated with true cryptographic randomness — ideally one unique password per account, stored in a password manager.

This password generator creates passwords using your browser's crypto.getRandomValues(), so every password is as strong as the hardware allows. Adjust the length up to 128 characters, toggle uppercase, lowercase, numbers and symbols, exclude ambiguous characters (0/O, 1/l/I), and watch the entropy estimate — a measure of how hard the password is to guess.

Frequently asked questions about the Strong Password Generator

Here are the answers to the questions people ask most about the Strong Password Generator.

• How strong should my password be? — Aim for at least 12 characters using all character types — 16+ is better for important accounts. Length beats complexity in practice.
• What is password entropy? — Entropy measures how many guesses an attacker would need, in bits. 50+ bits resists online attacks; 80+ bits is effectively uncrackable by brute force.
• Should I use the same password everywhere? — Never. Use a unique password per account and store them in a password manager — that way one breach cannot cascade to your other accounts.
• Are generated passwords stored anywhere? — No. Generation happens locally in your browser and nothing is transmitted, logged or stored.
