What is a UUID or GUID?
A UUID (Universally Unique Identifier), often referred to as a GUID (Globally Unique Identifier) in the Microsoft ecosystem, is a 128-bit label used for information in computer systems. Its main advantage is that it is "practically unique" without requiring a central database to verify duplication.
The UUID v4 generated by our tool relies on pseudo-random numbers, making it highly suitable for database primary keys, session IDs, or tracking codes. If you are looking to generate secure passwords instead, we suggest using our Secure Password Generator, which is specifically designed for that purpose.
Frequently Asked Questions
UUID v1 is generated using the computer\'s MAC address and the current timestamp, which means it can potentially be traced back to its origin. UUID v4, on the other hand, is completely random, making it much better for privacy and security.
Not at all! Our algorithm is highly optimized. Generating 500 or even 1000 UUIDs takes a fraction of a second directly on your browser.
