Password Generator details
First, enter Length in Password Generator. Next, review Password and Entropy (bits). Additionally, Password Generator uses 6 input fields and 2 output blocks so the result is easy to scan and copy.
Build a strong random password using crypto.getRandomValues with rejection sampling for uniform distribution. Pick the length (4;128), toggle uppercase, lowercase, digits and symbols, and optionally exclude characters that look alike (0/O/1/l/I). The entropy in bits is reported so you can judge strength. Runs entirely in your browser.
