Are the generated passwords truly random?

Yes. The generator uses the Web Crypto API (window.crypto.getRandomValues), which provides cryptographically secure pseudo-random numbers — the same source used by password managers and security libraries.

What makes a password "strong"?

Strength comes from length and character variety. A 16-character password mixing uppercase, lowercase, digits, and symbols has roughly 95^16 possible combinations — far beyond what brute-force attacks can feasibly crack.

When should I use a UUID instead of a password?

UUIDs are designed as unique identifiers, not secrets. Use them for database primary keys, correlation IDs, and idempotency keys. Use passwords (or long random tokens) when you need a secret that cannot be guessed.

Generate Secure Passwords Online

Weak passwords are one of the most common entry points for security breaches. Generating a truly random, high-entropy password — and then verifying that it meets the strength requirements of your application or security policy — used to require installing a separate utility. devtoolkit.sh's Password Generator creates strong random passwords of any length using your chosen mix of uppercase letters, lowercase letters, digits, and special symbols. The generation runs in your browser using the Web Crypto API, which provides cryptographically secure random values — the same standard used by password managers. After generating a password, run it through the Password Strength Checker to see its estimated entropy and whether it would survive common brute-force attacks. If you need random identifiers for database records, API keys, or session tokens rather than human-memorable passwords, the UUID Generator produces RFC 4122-compliant version 4 UUIDs that are statistically guaranteed to be unique.
