Password Generator – Free Online Tool

How to Generate Strong Passwords

1. Set your desired password length (12+ recommended)
2. Select character types to include
3. Click "Generate Password"
4. Copy your new secure password

Password Security Tips

• Length Matters: Use at least 12 characters, 16+ is better
• Mix Characters: Include uppercase, lowercase, numbers, and symbols
• Unique Passwords: Use different passwords for each account
• Password Manager: Consider using one to store passwords securely
• Never Share: Don't share passwords via email or text

Why Random Passwords Matter

Most data breaches happen because people reuse weak passwords across multiple accounts. When one service is compromised, attackers try the same credentials on banking, email, and social media sites—a technique called credential stuffing. A unique, randomly generated password for every account stops this attack in its tracks.

Human-chosen passwords tend to follow predictable patterns: a capitalised word, a number, and a symbol at the end (e.g., "Summer2025!"). Automated cracking tools test these patterns first, making such passwords far weaker than their length suggests. Truly random passwords have no pattern for attackers to exploit.

How Password Strength Is Measured

Password strength is often measured in bits of entropy. Entropy depends on the size of the character set and the password length. For example:

• A 12-character password using lowercase letters only (26 chars): ~56 bits of entropy
• A 12-character password using upper + lower + digits + symbols (~95 chars): ~79 bits of entropy
• A 16-character password using the full set: ~105 bits of entropy

Security experts generally recommend at least 80 bits of entropy for important accounts. Our strength meter gives you a visual indicator so you can see exactly where your password stands.

Best Practices for Managing Passwords

• Use a password manager: Tools like Bitwarden, 1Password, or KeePass store all your passwords securely behind one master password.
• Enable two-factor authentication (2FA): Even a strong password can be phished. 2FA adds an extra layer of protection.
• Never share passwords: Legitimate services will never ask for your password via email or phone.
• Change passwords after breaches: If a service you use is breached, change that password immediately.
• Avoid storing passwords in plain text: Don’t keep passwords in sticky notes, spreadsheets, or unencrypted files.

Limitations

This tool generates passwords but does not store them. If you close the page without copying your password, it is lost forever. For ongoing password management, we recommend pairing this tool with a dedicated password manager.
