Password Generator
Create a high-entropy random password locally using the browser cryptographic random-number generator.

Approx. entropy0 bitsEstimate assumes uniform independent choices.
How this tool works
Characters are sampled with crypto.getRandomValues. The page also estimates entropy from password length and selected alphabet size assuming independent uniform samples.
Example
Select 24 characters with upper, lower, digits and symbols to produce a fresh password and copy it directly.
Common questions
Does CrunchAnything receive the generated password?
No. Generation happens locally in the browser.
What does the entropy number mean?
It is a theoretical estimate based on the selected character pool and length, not a guarantee against weak handling, reuse, phishing or compromised devices.
