What is the Password Generator?
The Password Generator creates cryptographically secure, random passwords of any length using combinations of uppercase letters, lowercase letters, numbers, and symbols. All generation uses the browser's crypto.getRandomValues() API. No passwords are ever transmitted or stored.
Password Strength Guidelines
| Length | Character Sets | Security Level |
|---|---|---|
| 8 chars | Numbers only | Very weak, crackable instantly |
| 12 chars | Upper + Lower + Numbers | Good, suitable for most accounts |
| 16 chars | All character sets | Strong, recommended (NIST 2023) |
| 20+ chars | All character sets | Very strong for critical accounts |
Common Use Cases
- Generate strong unique passwords for new account registrations
- Create API keys, secret tokens, or database passwords for applications
- Generate memorable passphrases or PIN codes
- Create temporary passwords to share with users who must reset on first login
Frequently Asked Questions
1. Is the password generator truly random?
Yes. It uses crypto.getRandomValues(), the browser's cryptographically secure random number generator, not a predictable pseudorandom algorithm.
2. Should I use a password manager?
Yes. Generating unique, strong passwords for every site is only practical with a password manager (1Password, Bitwarden, etc.). Never reuse passwords across accounts.
