Accessible offline security tool
Password Strength Checker
Password Strength Checker evaluates passwords fully in the browser. It estimates entropy, detects weak patterns such as repeats and sequences, announces strength updates accessibly, and includes a built-in password generator.
Problem
Many password tools are either opaque, network-dependent, or inaccessible to users who need clear feedback while typing.
Solution
This project keeps checks local, explains strength signals in plain language, and uses accessible live updates so the interface works for more users.
Outcome
A practical public frontend component that demonstrates security UX, accessibility, and offline-friendly implementation.
