Frequently Asked Questions
How long should my password be?
At minimum, use 12 characters. For better security, 16-20 characters is recommended. Each additional character exponentially increases the number of possible combinations, making brute-force attacks impractical.
What makes a password strong?
A strong password uses a mix of uppercase letters, lowercase letters, numbers, and special characters. It should be at least 12 characters long and avoid common words, patterns, or personal information like birthdays.
Is this password generator secure?
Yes. All passwords are generated using the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. Passwords are generated entirely in your browser and never sent to any server.
Should I use a different password for every account?
Absolutely. Reusing passwords is one of the biggest security risks. If one account is breached, all accounts with the same password are compromised. Use this generator to create unique passwords for each account.
What are ambiguous characters?
Ambiguous characters are those that look similar in certain fonts: l (lowercase L), I (uppercase i), 1 (one), O (uppercase o), and 0 (zero). Enable "No ambiguous chars" to exclude them and avoid confusion when typing passwords manually.
How does password strength work?
Password strength is estimated based on the character pool size and password length. It calculates the number of possible combinations and estimates how long it would take to brute-force the password at 10 billion guesses per second.
Can I generate multiple passwords at once?
Yes! Use the batch count slider to generate 1-20 passwords at once. All passwords are generated independently with the same settings. Each one in the batch list has its own copy button.
How should I store my passwords?
Use a password manager like Bitwarden, 1Password, or KeePass to securely store your passwords. Never write passwords on sticky notes or store them in plain text files. Enable two-factor authentication whenever possible.
