Frequently asked questions
Is a GUID the same as a UUID?
Yes. GUID is Microsoft's name for the same 128-bit identifier format.
Can two v4 UUIDs collide?
In practice, no. There are 2¹²² possible values, so a collision is astronomically unlikely.
Should I use UUIDs as passwords?
No. Use the Password Generator for secrets.
