FAQ Frequently Asked Questions

What is the difference between UUID versions?

This tool generates UUID version 4 (random), which is the most commonly used type. UUID v4 uses cryptographically secure random numbers, making collisions extremely unlikely. Other versions use timestamps or MAC addresses.

How unique are these UUIDs really?

UUID v4 has 122 bits of entropy, making the probability of generating a duplicate essentially zero. You could generate a billion UUIDs per second for the next 100 years and still not expect a single duplicate.

Can I use these UUIDs as database primary keys?

Yes, UUIDs make excellent primary keys, especially for distributed systems. They are globally unique, do not reveal information about your data volume, and work well across multiple databases or systems.

Why generate 10 UUIDs at once?

Generating multiple UUIDs at once is convenient for bulk operations like setting up test data, creating multiple database records, or when you need several unique identifiers for a project. You can copy them individually or all at once.

Are these UUIDs cryptographically secure?

Yes, the UUIDs are generated using cryptographically secure random number generation provided by your browser. This makes them suitable for security-sensitive applications where unpredictability is important.
