Quick Security Reference
- Random Passwords: Best for automated password managers (Bitwarden, 1Password). Aim for 16+ characters.
- Passphrases (Words): Best for master passwords you need to memorize and type manually. 4+ words recommended.
- PIN Codes: Use only where letters aren't allowed (device locks). 6+ digits are significantly safer than 4.
How to Use the Advanced Password Generator
- Select your Generator Type: Random (standard), Passphrase (memorable words), or PIN Code.
- Adjust the Length slider to set character count, word count, or PIN length.
- Toggle character types (uppercase, numbers, symbols) or word separators to fit the website's rules.
- Enable Bulk Generation if you need a list of up to 100 secure passwords instantly.
- Click Copy to send the secure string directly to your clipboard.
What is a Memorable Passphrase? (Diceware)
A passphrase is a string of random dictionary words combined together (e.g., Horse-Battery-Staple-Correct). Because it uses entire words, humans can easily memorize and type it. Because the words are selected with cryptographic randomness from a large dictionary, computers find it incredibly difficult to crack. A 4-word passphrase can take thousands of years for a hacker to brute-force, making it the perfect master password for your vault or computer login.

Frequently Asked Questions
Are these passwords truly random?
Yes. We use the modern browser window.crypto.getRandomValues() API. Unlike older math-based randomization, this generates cryptographically secure, unpredictable values.
How is the password strength calculated?
It is based on cryptographic "entropy" (measured in bits), which mathematically factors in the length of your password and the size of the character pool. A password with over 80 bits of entropy is considered "Very Strong" and would take modern supercomputers trillions of years to guess.
Can I retrieve a password if I forgot to save it?
Yes, click the "History" icon (clock) at the top of the generator to view your recently generated passwords. However, because this tool is 100% private, if you clear your browser data they will be wiped.
Why should I avoid similar characters?
Characters like capital 'O' and zero '0', or lowercase 'l' and number '1', can be confused by the human eye depending on the font. Checking "Exclude Similar" removes these characters to prevent typos.
