Frequently Asked Questions
Are these UUID v4?
Yes, generated with version and variant bits set.
Are they globally guaranteed unique?
No absolute guarantee exists, but UUID v4 collision probability is extremely low.
When to use a UUID
A version 4 UUID is a random 128-bit identifier that is very unlikely to repeat, which makes it handy for database keys, file names and test data without a central counter.
Do not use a UUID as a secret or an access token. For secrets, use the password generator, which is designed for that purpose.
