Bootstrap Show Password Toggle

A show password as text toggle for Bootstrap forms

• Native-looking UI
• Vanilla JavaScript with no dependencies
• Base64 encoded SVG icons (no external images or fonts required)
• Graceful fallback for browsers with JavaScript disabled
• Works with Bootstrap 4 and 5
• Supports dark mode (Bootstrap 5 only)
• Only 1KB gzipped

Quick Start

• Download the latest release
• Clone the repo git clone https://github.com/coliff/bootstrap-show-password-toggle.git
• Install with npm npm install bootstrap-show-password-toggle
• Install with yarn yarn add bootstrap-show-password-toggle

Usage

1. Include the show-password-toggle.min.css in your CSS

2. Wrap the password input in an input-group div as follows:

<div class="input-group">
  <input type="password" class="form-control rounded" required>
  <button id="toggle-password" type="button" class="d-none"
    aria-label="Show password as plain text. Warning: this will display your password on the screen.">
  </button>
</div>

3. Load the show-password-toggle.min.js after the form

I highly recommend adding the attributes: spellcheck="false", autocorrect="off" and autocapitalize="off" to the password input so that when the password is displayed in plain text the input is not auto-corrected, capitalized or spellchecked (to avoid red squiggly line underneath).

You should also add name="current-password" and autocomplete="current-password" to help browsers autocomplete the form.

Demo

• Bootstrap 5 Demo
• Bootstrap 4 Demo

Browser Support

Works well with all the browsers supported by Bootstrap

FAQS

Q. Can I change the show password icon?

A. Yes you can change the icon displayed by replacing the .input-password[type="password"] Base64 encoded background image. SVG is recommended.

Known Issues

• If the browser autofills the password input then the user-agent will apply background-image: none !important.
• The password input requires the use of the required attribute. This is so the background-image is not displayed when the input is empty. (It'd be great if browsers supported the :blank pseudo-selector!)
