Frequently Asked Questions
- What version of UUID is generated?
- UUID v4, which uses cryptographically secure random numbers. Each UUID has 122 random bits.
- How are the UUIDs generated?
- We use crypto.randomUUID() when available, with a fallback to crypto.getRandomValues(). Math.random() is never used.
- Are the generated UUIDs truly unique?
- With 2^122 possible values, the probability of collision is astronomically low — effectively zero for any practical use.
- What is the maximum quantity?
- You can generate up to 100 UUIDs at once. For larger batches, generate multiple times.
