Abstract: A system and method are disclosed for providing an extensible email having rich, interactive browser capabilities. The system includes a service provider for receiving extensible emails from a third party platform and presenting the emails to a user's computing device. The extensible email includes URL metadata which allows a mail user agent to fetch and run code from a third party server in order to generate the extensible email. A secure sandbox ensures that the third party code does no damage to the service provider system or the user's computing system.

Abstract: A method for providing an additional layer of authentication prior to accessing a user's account even though the user's credentials have previously been verified. User accounts are often accessed via a sign-in page that verifies the user's credentials. Upon detecting a device accessing the sign-in page, an identifier associated with the device is obtained. One such type of identifier is the IP address assigned to the device. Based on the identifier, it is determined whether the device is trusted or not. Even thought the user's credentials are verified via the sign-in page, if the device is not trusted, a second authentication page is presented to the user prior to proceeding to the account. The second authentication page presents at least one security question. The security question is based on information contained in the user's account (e.g., contact information, event information, electronic messages, etc.). The user is required to correctly answer the security question in order to access the account.
