Generate UUID v4 identifiers and random passwords in the browser

Choose the output type

Open the generator (Chinese interface), select UUID v4, enter a quantity of 3 and generate. Expect three identifiers in hexadecimal 8-4-4-4-12 groups. The third group starts with 4; the fourth starts with 8, 9, a or b. Random outputs should not be compared with a fixed tutorial string.

Generate passwords

Select random passwords, a quantity of 3 and a length of 24. The current implementation requires uppercase, lowercase, digits and supported symbols in each result, and avoids some ambiguous characters. Verification checks format and length, rather than retaining passwords for real use.

Respect the limits

Quantity must be an integer from 1 to 100. Password length must be an integer from 12 to 128. The password-length field does not change UUID format. If a destination excludes certain symbols, follow its requirements; the tool does not offer an arbitrary custom character set.

Distinguish the purpose

A UUID identifies an object or request. Uniqueness is not authorization. A password is a secret accepted by a particular system. An API key must be issued by the service and connected to account permissions; generating a random string does not grant API access.

Store results intentionally

Copy or download successful output and place actual passwords in an appropriate password manager. The tool does not retain generation history. A downloaded text file is not encrypted. Do not include real passwords in shared screenshots or repositories. Browser cryptographic randomness does not amount to a mathematical guarantee that a collision can never occur.
