    UUID v4 values from crypto.randomUUID().

    Treat tokens as secrets and copy them directly to secure storage.

    How to use

    How does it work?

    Choose UUID or token, set quantity and length, then generate and copy.

    Privacy

    Does this use Math.random()?

    No. UUIDs and tokens both use the browser Web Crypto API.

    Limits and guidance

    Security limits

    A token is random data; it does not create authorization, expiration, or revocation by itself.
