The signature is valid for a limited time, can only be used once, and users cannot request multiple signatures. The signature may be **public**. Even if someone else obtains the signature, they cannot use it on their behalf. The signature is bound to the intended recipient, ensuring that only the rightful user can claim the associated tokens. Additionally, the receiver has the option to delegate the `dispenseLock` call to an approved address.
