About Password Security
Creating strong, unique passwords is one of the most important steps you can take to protect your online accounts. This password generator uses cryptographically secure random number generation to create passwords that are virtually impossible to guess or crack.
How It Works
This tool generates passwords using your browser's built-in crypto.getRandomValues() API, which provides cryptographically secure randomness. Unlike simple random number generators,
this method ensures that passwords are truly unpredictable and suitable for securing sensitive
accounts.
Best Practices
- Use different passwords for different accounts
- Make passwords at least 12-16 characters long
- Include a mix of uppercase, lowercase, numbers, and symbols
- Store passwords securely in a password manager
- Never share passwords via email or messaging apps
- Change passwords if you suspect an account has been compromised
Privacy & Security
Your privacy is important. All password generation happens entirely in your browser—no data is sent to any server. The passwords are generated on-demand and exist only in your browser's memory. They are never logged, stored, or transmitted anywhere.
Frequently Asked Questions
Common questions about password generation and security
How secure are the generated passwords?
The passwords are generated using the browser's built-in cryptographic random number generator (crypto.getRandomValues()), which provides cryptographically secure randomness. This makes the passwords highly unpredictable and suitable for securing sensitive accounts.
Are the passwords stored or sent anywhere?
No, all password generation happens entirely in your browser. Nothing is stored, logged, or sent to any server. Your passwords remain completely private and are only visible to you.
What makes a password strong?
A strong password has sufficient length (at least 12-16 characters), uses a mix of character types (uppercase, lowercase, numbers, symbols), and is completely random. Avoid using dictionary words, personal information, or predictable patterns.
What does "exclude ambiguous characters" mean?
Ambiguous characters are those that look similar and can be confused, such as 0 (zero) and O (letter O), or 1 (one), l (lowercase L), and I (uppercase i). Excluding them can make passwords easier to read and type manually.
How long should my password be?
For most accounts, a password of 12-16 characters is sufficient. For highly sensitive accounts (banking, email), consider 20+ characters. Longer passwords are exponentially more secure against brute-force attacks.
