📚 Password Security Guide

🔹 Why Strong Passwords?

Weak passwords can be cracked in seconds. Strong passwords protect your email, banking, social media, and personal data from hackers and identity theft.

🔹 What Makes a Password Strong?

  • Length (12+ characters)
  • Character variety
  • No dictionary words
  • No personal information
  • Random generation

🔹 Password Managers

Use a password manager to generate and store complex passwords. You only need to remember one master password. Popular options: LastPass, 1Password, Bitwarden.

🔹 Two-Factor Authentication

Always enable 2FA when available. It adds an extra layer of security even if your password is compromised.

❓ Frequently Asked Questions

How often should I change my passwords?

Change passwords immediately if you suspect a breach. Otherwise, good strong passwords can be used for years. Focus on unique passwords for each account rather than frequent changes.

What is password entropy?

Entropy measures password randomness in bits. Higher entropy means harder to crack. 50+ bits is good, 80+ bits is excellent. Our generator creates passwords with high entropy.

Are generated passwords stored anywhere?

No! All passwords are generated locally in your browser. They are never sent to any server. Your privacy and security are our priority. Only history is stored locally on your device.

Should I use special characters?

Yes! Special characters dramatically increase password complexity and cracking time. However, ensure the website accepts them - some systems restrict certain characters.

⚠️ Security Note: This generator creates strong passwords locally. However, always follow platform-specific requirements and use additional security measures like two-factor authentication.
