Features

Passliss offers a wide range of security-focused features:

Password Generator

The Generate page offers complete flexibility for creating random passwords:

• Choose the exact length
• Include or exclude symbols, numbers, uppercase or lowercase characters
• Generate multiple passwords in one click
• Export results as a CSV for secure storage or transfer

It also includes a simplified mode for quick generation and an advanced mode for fine-tuning every detail.

Passliss also integrates OpenAI’s GPT-4o-mini to let you generate secure passwords from natural language prompts. Whether you want a password that's "12 characters, includes symbols and is easy to remember" or "a banking-grade passphrase," the AI adapts to your needs and delivers strong, context-aware results.

Strength Analysis

Easily evaluate the security of any password. The Strength page provides:

• A real-time strength score

• Detailed suggestions for improvement

• Visual indicators and contextual tips This helps users better understand how to avoid weak or easily guessable passwords.

Encryption & Decryption

Secure strings using trusted algorithms like AES and Triple-DES. Hashing support is also included.

Customization

You can modify default settings, themes, and presets via the Settings page in the app. Presets are pre-defined configurations for the password generator, allowing you to quickly select a set of options that suit your needs.
