Are the generated passwords secure?

Yes. They're produced using the browser's cryptographically secure random number generator and never leave your device, so no one else sees them.

What is a UUID used for?

A UUID is a 128-bit identifier that's practically guaranteed to be unique, used for database keys, request IDs, and resource names without needing a central authority to assign them.

Are generated values sent to a server?

No. Everything is generated locally in your browser.

Generated Output

Generate strong random passwords and UUIDs in your browser. Control length and character sets for passwords, or produce RFC-compliant UUIDs for keys and identifiers. Values are created locally with the browser's secure random generator — never transmitted.

How to generate a password or UUID

1Choose password length and which character types to include, or pick UUID.
2A new strong value is generated instantly using cryptographically secure randomness.
3Copy it and regenerate as many as you need.

What makes a password strong

Strength comes from length and unpredictability. A long password drawn from a large character set (upper, lower, digits, symbols) using a cryptographically secure random source is extremely hard to guess or brute-force. This generator uses the browser's secure randomness, not a predictable algorithm.
