UUID Generator questions
Short answers, then the practical details.
What is a version 4 UUID?
A version 4 UUID is a 128-bit identifier with 122 random bits and fixed version and variant bits. The text representation uses five groups of hexadecimal digits separated by hyphens.
Can I generate UUIDs in bulk?
Yes. Enter any whole number from 1 to 1,000. Each click creates a fresh batch that you can copy or download.
Can I use a UUID as a password?
UUIDs are intended as identifiers. Do not rely on them to protect access to a file, account or resource. Use purpose-built secrets and access controls for that.
