About this tool
This password generator builds random strings in your browser using the Web Crypto API (crypto.getRandomValues). You choose length and character classes; optional filtering removes look-alike characters such as I/l/1 and O/0. Generated passwords are never sent to QSTools.
FAQ
- Are passwords uploaded?
- No. Generation and optional copy stay on your device.
- Is the randomness secure?
- We use crypto.getRandomValues with rejection sampling to avoid modulo bias. That is suitable for everyday account passwords; password managers remain a better long-term habit.
- What does “exclude ambiguous” do?
- It removes characters that are easy to confuse when you read or type a password (for example I, l, 1, O, and 0).
