Frequently Asked Questions
What is the difference between UUID v1 and v4?
UUID v1 is generated from a timestamp and the computer’s MAC address, which makes it unique across space and time but reveals the creation time and machine identity. UUID v4 is purely random (122 random bits), with no embedded information.
Can I use these UUIDs for passwords?
You can, but we don’t recommend it. UUIDs are designed to be unique, not cryptographically unpredictable for security purposes. For passwords, a dedicated password generator is safer.
Is the generation privacy‑safe?
Yes. All UUIDs are computed entirely in your browser. No data is uploaded, so your UUIDs remain private.
