About the Password Generator
Strong passwords need real randomness, not a memorable pattern. This generator uses crypto.getRandomValues — the same cryptographically secure random number source browsers use for keys and tokens — rather than Math.random(), and shows an entropy-based strength estimate so you can see exactly how much randomness a given length and character set actually provides.
Key Features
- Adjustable length, character sets, and an option to exclude visually ambiguous characters (il1Lo0O).
- Live entropy calculation in bits, with a strength label.
- Batch-generate multiple passwords at once.
