Password Generator

What is a Secure Password?

A secure password is one that is difficult for others to guess or crack through brute force. It combines sufficient length (at least 12–16 characters for most use cases), a variety of character types (uppercase, lowercase, numbers, symbols), and avoids common patterns like dictionary words or predictable sequences. The longer and more varied a password is, the harder it is to crack.

Best Practices

Follow these guidelines when creating passwords:

• Length: Use at least 12 characters; 16 or more is recommended for sensitive accounts
• Variety: Include uppercase, lowercase, numbers, and symbols when allowed
• Avoid dictionary words: Random combinations are stronger than words or phrases
• Unique per account: Never reuse passwords across different services
• Exclude ambiguous characters: For manual entry, avoid 0/O, 1/l/I to reduce typing errors

How to Use the Generator

Set the desired length (8–128 characters), check the character types you want (uppercase, lowercase, numbers, symbols), and optionally enable "Exclude ambiguous" to avoid easily confused characters. Click Generate to create a new password. Use the Copy button to copy it to your clipboard. The strength indicator shows whether the password is weak, medium, or strong based on length and character variety.

Examples

Example 1: A 16-character password with all character types: K7m#pQ2x@vN9wL4j. Suitable for most online accounts.

Example 2: A 24-character password with symbols for high-security use: Tr8$kP#mX2vQ9wL5j@nB4hF. Ideal for password managers or sensitive applications.

Frequently Asked Questions

What is the minimum password length?

We recommend at least 12 characters. The generator supports 8–128 characters. Many services require a minimum of 8; use 16 or more when possible.

What are ambiguous characters?

Ambiguous characters look similar and can cause typing errors: 0 (zero) and O (letter O), 1 (one) and l (lowercase L) and I (uppercase i). Excluding them helps when you need to type the password manually.

Is it safe to use this tool?

Yes. All password generation happens in your browser using crypto.getRandomValues(), a cryptographically secure API. No password is ever sent to any server. Your passwords never leave your device.

Can I use these passwords for sensitive accounts?

Yes, the randomness is cryptographically secure. However, use a password manager for important accounts and enable two-factor authentication when available. Use this tool responsibly.

Why should I include symbols?

Symbols increase the character set, making brute-force attacks much harder. Each additional character type exponentially increases the number of possible combinations.

Disclaimer

Use this tool responsibly. All generation is client-side; no data is sent to the server. Do not use for sensitive accounts without additional security measures such as two-factor authentication.
