Good to know
UUID v4 identifiers are random. Generate up to 1,000, one per line. Identifiers are not a substitute for authentication tokens or passwords.
How many: 5
Understand and use your results
Generate random identifiers for test data or objects. UUID v4 is not a readable sequence number and does not encode a creation timestamp.
How to use it
- Choose a quantity between 1 and 1,000.
- Use each generated line as one identifier or download the text.
Worked example
count: 2
xxxxxxxx-xxxx-4xxx-[89ab]xxx-xxxxxxxxxxxx xxxxxxxx-xxxx-4xxx-[89ab]xxx-xxxxxxxxxxxx
This is a format illustration, not an actual generated value. Each x is a hexadecimal digit, and [89ab] means one of those four digits. Running the tool produces random identifiers.
Is uniqueness absolutely guaranteed?
Collisions are extremely unlikely but not mathematically impossible. Use a uniqueness constraint for important database records. Do not treat knowledge of an identifier as authentication or use it in place of a password.
