Tokens versus IDs

A secure token is intended to be hard to guess. A UUID identifies an item with very low collision risk, but it should not be treated as a password or authorization secret. Use Secure Token Generator for secrets and UUID Batch Generator for public record identifiers.

Choose a token length

Enter a byte count from 1 to 1024. The generator calls the browser’s cryptographic random source and prints hexadecimal text, two characters per byte. For an ordinary application secret, 32 random bytes provide 256 bits of raw entropy. Store it securely; the tool does not save it or email it.

Make IDs in a batch

Enter a count from 1 to 1000 in UUID Batch Generator. Each output is a new UUID v4. Check the destination system’s preferred format and uniqueness constraints before importing a batch.

Handle secrets responsibly

Avoid pasting tokens into public issue reports, URLs, screenshots or analytics fields. A locally generated token still needs safe storage, access controls and rotation if exposed.

A small worked example

Entering 32 in Secure Token Generator yields 64 hexadecimal characters, because each byte becomes two hex digits. Running it twice should produce unrelated values. Entering 5 in UUID Batch Generator yields five separate version 4 identifiers. Use the token as a private secret, and use UUIDs only as IDs; neither tool provisions an account or stores its output.
