🎲 UUID & Random Token Generator
Generate RFC 4122 compliant UUID v4 identifiers and cryptographically random API tokens in batch. Fast, secure, and generated locally in your browser.
Cryptographic Entropy & Safety
ToolsHub uses the browser's native crypto.getRandomValues() CSPRNG (Cryptographically Secure Pseudo-Random Number Generator). The probability of generating a duplicate UUID v4 collision is approximately 1 in \(2.71 \times 10^{18}\), guaranteeing absolute uniqueness across distributed architectures.
How to use UUID & Token Generator
Choose UUID or token options, set the quantity and generate values. Copy the identifiers into your application.
What to check before using the result
Store generated secrets securely. Random identifiers are not a replacement for authorization checks.
Example: Creating test record identifiers
Select UUID v4 and generate five identifiers for sample records. Hyphens, capitalization, braces and quotes change presentation. A random ID should still be checked against any uniqueness constraints in your application.
