About UUIDs
UUID (Universally Unique Identifier) is a 128-bit label used for information in computer systems. The probability that a UUID will be duplicated is close to zero.
UUIDs are useful when:
- You need unique identifiers without a central coordination mechanism
- You need to identify information across distributed systems
- You want to create identifiers that can't be easily guessed
The UUIDs generated by this tool are version 4 UUIDs, which are randomly generated.
