Password Gen is a free generators tool that runs entirely in your browser — strong, configurable, entropy meter. No upload, no account, no limits.
Generate strong, configurable passwords with a live entropy estimate. Choose the length and which character sets to include — uppercase, lowercase, digits and symbols — and a strength meter shows the bits of entropy. Built on the browser's secure random generator.
Yes — passwords use crypto.getRandomValues, not Math.random.
It estimates strength in bits from the length and character pool; higher is harder to brute-force.
Every calculation happens on this page, in your own browser. Your input is never sent to a server, never logged and never used for training — which also means the tool keeps working when you are offline.
