How to use this tool
Choose how many UUID version 4 identifiers to generate, then click Generate UUIDs. Copy the resulting identifiers or download them as a TXT file.
Quick steps
- Select how many random version 4 identifiers to create.
- Generate the IDs using browser-based cryptographic randomness.
- Copy the UUIDs or download a text file.
Practical tip
UUID v4 identifiers are designed to have an extremely low collision probability, but they do not grant access rights and must not be treated as passwords or confidential tokens.
Common questions
Are these version 4 UUIDs?
Yes. Each identifier has the correct version 4 and RFC variant bits, using cryptographic browser randomness.
Can I generate multiple identifiers?
Yes. Generate up to 50 UUIDs per batch, then copy or download the list.
Can I use a UUID as a password?
A UUID is an identifier, not a recommended replacement for a purpose-built authentication secret.
