Password Generator
Create strong random passwords using cryptographic randomness. Control length and character sets, see strength and copy instantly.
Runs entirely in your browser — no uploadsAbout this tool
Password Generator builds passwords from crypto.getRandomValues with rejection sampling for unbiased picks — no modulo bias, no weak randomness.
Tune length and character classes (upper, lower, digits, symbols), exclude look-alikes like O0lI1, and watch the entropy estimate update live. Nothing generated here is ever transmitted or stored.
FAQ
Are these passwords safe to use?
Yes. They are drawn from your browser’s cryptographic RNG on your own device and are never logged, transmitted or stored.
What is entropy?
It measures unpredictability in bits. 70+ bits is considered very strong against modern cracking attempts.
Why exclude look-alike characters?
Ambiguous pairs like O/0 or l/1 cause transcription errors when passwords must be typed manually.
