What are UUIDs?
A UUID (Universally Unique Identifier) is a 128-bit number used to identify information in computer systems. The standard is described in RFC 4122.
- Uniqueness: extremely low probability of duplication
- Security: difficult to predict
- Decentralization: generated locally without central coordination
- Wide application: databases, distributed systems, APIs
Our generator uses version 4 UUIDs which are completely random and provide the highest level of unpredictability.
