A UUID is a long random identifier that is practically unique, so different systems can create IDs without clashing. Developers use them for records, files and sessions.
How to generate
- Open UUID Generator.
- Enter how many you need, from 1 to 500.
- Choose uppercase or keep hyphens as you prefer.
- Copy the list.
Where UUIDs help
- Primary keys in databases.
- Names for uploaded files.
- Tracking and request IDs.
Not a secret
A UUID is unique, but it is not meant to be a password. Use proper security tools for secrets.
