What is a UUID?

A Universally Unique Identifier, a 128-bit label used to uniquely identify information in computer systems.

Can two UUIDs be the same?

While technically possible, the probability is so infinitesimally small that they are considered unique globally.

What is the difference between V1 and V4?

V1 is time-based (sequential); UUIDv4 is purely random, which is safer for security applications.

Database Primary Keys

Use UUIDs as primary keys in distributed database systems to prevent collision issues.

Software Development

Generate unique session tokens, transaction IDs, or object identifiers in application backends.

URL Obfuscation

Use a UUID instead of a sequential ID in a URL to prevent users from easily guessing other resource links.
