    🛠 How To Use The Password Generator 

    This tool helps you create secure, random passwords based on your preferences. Follow these steps to customize and generate your perfect password. 

    1️⃣ Password Length (Slider) 

       • Move the slider to set the number of characters in your password. 

       Tip: Aim for at least 15 characters for maximum security. 

    2️⃣ Character Options 

    Select the types of characters you want: 

       • Include lowercase (a–z) → small letters. 

       • Include UPPERCASE (A–Z) → capital letters. 

       • Include Numbers (0–9) → digits. 

       • Include Symbols (!@#$…) → special characters for extra complexity. 

    3️⃣ Advanced Options 

    Fine-tune your password: 

       • Exclude Ambiguous Chars (O, 0, l, 1, I) → avoids lookalike characters. 

       • No repeating Characters → each character appears only once. 

       • Pronounceable → consonant–vowel pattern for easier pronunciation. 

       • Pattern (Optional)

           o L = Letter 

           o N = Number 

           o S = Symbol 

           o ? = Any character 

    o Example: LNL-SLNN = Letter, Number, Letter, dash, Symbol, Letter, Number, Number. 

    4️⃣ Generate Password  

    Click Generate to instantly create your password based on your chosen settings. 

    5️⃣ Download.txt 

    Save your generated password(s) as a .txt file (store securely). 

    6️⃣ Clear History 

    Deletes all previously generated passwords from the list. 

    7️⃣ Copy 

    Copies the current password to your clipboard. 

    8️⃣ Regenerate 

    Creates a new password using your current settings. 

    9️⃣ Strength 

    Displays password strength metrics: 

       • Entropy (Bits): Higher = more secure. 

       • Guess Time: Estimated crack time. 

       • Charset Size: Number of unique characters used. 

       • Mode: Random, pattern, or pronounceable. 

    🔟 History 

    Lists all passwords generated in this session. 

    1️⃣1️⃣ Paste History 

    Quickly reuse a password from history

    💡 Security Tip

    Always store passwords in a secure password manager. Never reuse the same password across accounts. 🔍 Password Strength – What It Really Means When you generate a password, you may see terms like Entropy, Guess Time, Character Set Size, and Generation Mode

    1️⃣ Entropy (Example: 104.12 Bits) 

       • Meaning: Measures unpredictability. 

       • Why It matters: Higher entropy = harder to guess. 

       • Example: 104 bits = extremely strong; virtually impossible to crack. 

    2️⃣ Guess Time 

    How long it would take to crack your password: 

       • Online (1,000/Sec) – slow attempts, like website logins. 

       • Single CPU (1M/Sec) – faster, one computer processor. 

       • GPU Cluster (10B/Sec) – high-performance cracking. 

       • Specialized Hardware (100T/Sec) – ultra-fast cracking machines. 

       • Pro Tip: If your guess time is billions/trillions of years, your password is rock solid. 

    3️⃣ Character Set Size (Example: 91) 

       • Meaning: Number of different characters available. 

       • Why It matters: Larger sets make guessing harder. 

       • Example: 91 includes uppercase, lowercase, numbers, and symbols. 

    4️⃣ Generation Mode (Example: Random) 

       • Random: No patterns or dictionary words; maximum unpredictability. 

    ✅ Pro Tip

    Password strength comes from Length + Randomness + Variety. Use a password manager and never reuse passwords.
