UUID Generator Online
Generate cryptographically strong UUID v4 identifiers.
Generate random version-4 UUIDs in the browser using the platform crypto API. Keep the source until you've opened and checked the downloaded result.
UUIDs are identifiers, not passwords.

This utility runs on the current device for the supported workflow. Kaazo does not need the pasted input to calculate the result.
UUID Generator: what the result contains
Generate random version-4 UUIDs in the browser using the platform crypto API.
A UUID is an identifier, not a secret
Random UUIDs are useful for reducing accidental collisions, but they shouldn’t be treated as passwords, access tokens or proof of authorization.
UUIDs are excellent identifiers, but they are not passwords, secrets or proof of authenticity.
When UUID Generator isn’t the right endpoint
Use a cryptographically designed token when possession of the value grants access.
Example and result checks
A product system can assign a UUID such as 123e4567-e89b-42d3-a456-426614174000 as an identifier in a database record. A version-4 UUID is intended to be difficult to collide with accidentally, not to prove who created it. Treat it as a label rather than a security credential.
Check whether your downstream database expects hyphenated strings, a binary representation or another format. Generate separate identifiers for separate records; do not reuse one merely because the values look random. Authentication tokens, password-reset links and access grants have different security requirements.
FAQ
What does UUID Generator actually do?
Generate random version-4 UUIDs in the browser using the platform crypto API.
What limitation matters most?
Random UUIDs are useful for reducing accidental collisions, but they shouldn’t be treated as passwords, access tokens or proof of authorization. UUIDs are excellent identifiers, but they are not passwords, secrets or proof of authenticity.
Does this replace a dedicated security or identity-verification service?
No. The tool performs the specific local operation described on the page. High-stakes signing, authentication, secret storage or compliance workflows can require specialised controls and audit trails.
