README

A small Roundcube plugin that adds a live password strength meter to the Settings → Password screen (provided by the official password plugin). It displays a color gradient bar and a label that updates as you type.

Features

• Zero-config: works with the standard Roundcube password plugin UI
• Color Gradient visual meter + textual label (Very weak → Very strong)
• Sensible heuristic: length, character variety, and simple pattern penalties
• Skin‑friendly, minimal CSS

Requirements

• Roundcube 1.5+ (tested with modern builds)
• The official password plugin enabled

Installation

1. Copy this folder to your Roundcube plugins/ directory as pwstrength_meter.
2. Enable it by adding to your Roundcube config (e.g. config/config.inc.php):

   $config['plugins'][] = 'pwstrength_meter';

3. Ensure the password plugin is enabled and accessible under Settings → Password.

No additional configuration is needed. The meter will appear under the "new password" input on the password page.

How it works

The plugin injects a small JS/CSS bundle only on the password page. The JS locates the most likely "new password" input (by name/id heuristics) and renders a 5‑segment meter beneath it. The score ranges 0–5 and is based on length, character class variety, and a few simple penalties for repeats and sequences.

Accessibility

• The meter exposes aria attributes and a text label announcing the current strength.

Customization

You can tweak colors and spacing in pwstrength_meter.css. The JS heuristic is in js/pwstrength_meter.js if you want a different scoring model.

Localization

Add files under localization/xx_XX.inc with a $labels array mirroring en_US.inc keys.
