Abstract
Architecture for generating a temporary account (e.g., an email address) with a user-supplied friendly name and a secret used to the sign the temporary account. For example, when a user wishes to create a temporary email address to use with an online organization, a friendly name is provided and the system generates a temporary email address including the friendly name. A signing component signs the temporary email address with a secret. One or more of these secrets can be provisioned prior to the user's creation of a friendly name, which eliminates propagation delay. During use, only incoming email messages having the temporary email address signed with the secret are validated. When the user revokes the temporary email address, the secret is revoked and the revocation is propagated to network gateways, rejecting any email sent to that address.
