About

In an era of brute-force attacks and rainbow tables, a simple password is a vulnerability. This utility generates cryptographically strong character strings entirely within your browser. Unlike server-side generators, your password never travels over a network. It emphasizes usability alongside security by offering phonetic pronunciation guides (to aid memory) and options to remove ambiguous characters (like I vs 1) that often cause login frustration.

Formulas

Entropy E is calculated based on the pool size R and length L.

E = L × log₂R

A pool of lowercase, uppercase, numbers, and symbols results in R ≈ 90.

Reference Data

Password Type	Entropy (approx)	Time to Crack (est.)	Use Case
8 Char (Lower)	37 bits	Instant	Avoid
10 Char (Mixed+Num)	59 bits	Hours/Days	Low Security
12 Char (Complex)	72 bits	Centuries	Standard Users
16 Char (Complex)	95 bits	Millennia	Recommended
20+ Char (Complex)	120+ bits	Heat Death of Univ.	Admin / Crypto Keys

Frequently Asked Questions

Yes. It uses the `crypto.getRandomValues()` API, which provides cryptographically strong random values suitable for security, rather than the predictable `Math.random()`.

These are characters that look identical in certain fonts, such as the number "0" and letter "O", or lowercase "l" (el) and uppercase "I" (eye). Removing them reduces transcription errors.

Complex passwords are hard to memorize. A phonetic mapping (e.g., "A" as in 'Alpha') helps the brain encode the string using verbal association rather than just visual memory.

Batch mode generates 50 distinct passwords at once. This is useful for system administrators who need to issue initial credentials for a large group of new users.
