High-Entropy Password Generator

📖 How to Generate Strong Passwords – Step by Step

• Step 1: Adjust the password length (6–64 characters) using the slider.
• Step 2: Select which character sets to include: uppercase, lowercase, numbers, symbols.
• Step 3: Optionally exclude ambiguous characters (like 1, l, 0, O) or prevent consecutive duplicate characters.
• Step 4: Add a custom prefix/suffix (e.g., company name or year).
• Step 5: Click “Generate New Password” – a cryptographically secure password appears instantly.
• Step 6: Click “Copy Password” to save it to your clipboard.

💡 Understanding Password Entropy

• ✔️ Entropy measures password strength in bits – higher is better.
• ✔️ 80+ bits is considered very strong for most purposes.
• ✔️ Our generator uses crypto.getRandomValues() for true randomness, the same standard used in secure HTTPS connections.
• ✔️ All processing happens in your browser – no passwords are ever sent over the network.
