Frequently asked questions

What is a UUID?
A Universally Unique Identifier - a 128-bit number used to uniquely identify information. UUID v4 is random, making it virtually impossible to generate duplicates.
Are these secure?
Yes. They use crypto.randomUUID() which relies on the browser's cryptographically secure random number generator - the same quality as system-level randomness.
What's UUID v4 vs other versions?
v4 is random - 122 bits of randomness. Other versions use timestamps (v1) or names (v5). v4 is the most common for general-purpose unique IDs.
