General Information Only
The content on this Site, including all explanations of UUID versions, RFC specifications, database recommendations, and code examples, is provided for general informational and educational purposes only. It is not intended as professional advice for any specific use case.
No Guarantee of Fitness for Purpose
UUIDs generated by this tool are produced using your browser’s built-in cryptographically secure random number generator (Web Crypto API). However, we make no guarantee that any generated UUID is suitable for your particular application, database system, security requirement, or compliance framework.
Security Disclaimer
UUID v4 provides high uniqueness through randomness but is not a cryptographic secret. Do not use UUIDs generated by any online tool as:
- Passwords or passphrases
- API secret keys or authentication tokens where unguessability is a security requirement
- Cryptographic nonces in security-sensitive protocols
- Session tokens where compromise could lead to account takeover
For security-critical secrets, use a purpose-built secret generator and store secrets using appropriate encryption and access controls.
Technical Accuracy
