Password Strength Checker

Overview

A browser tool based on the original Python password checker, combining a strength checklist, a configurable password generator and an encrypted local vault for website credentials.

Features

• Check length, uppercase, lowercase, digit and symbol criteria with clear suggestions
• Generate random passwords with configurable length and character types
• Save website passwords in a local vault protected by a master password
• Search saved entries and use automatic vault locking

Technology

• JavaScript
• Browser cryptography
• HTML & CSS

Using the app

Enter a password to see its checklist results or generate a new one. To use the vault, create a master password and add website entries. Password checks stay in the browser and do not test leaked-password databases. The local vault has no account synchronization or master-password recovery; clearing browser storage removes it.
