Systems and methods for enabling user authentication using a first computing device (e.g., a tablet computer) for providing user credentials including an obfuscated password to an application server for authenticating the user credentials and a second computing device different from the first computing device (e.g., a mobile phone) for generating the obfuscated password are described. In some cases, the first computing device may request a login page for accessing a protected resource (e.g., an electronic file) from the application server, which may generate a user specific grid for the login page and send the login page including the user specific grid to the first computing device. The user specific grid may include a plurality of symbols (e.g., alphanumeric characters) associated with a password. The second computing device may generate the obfuscated password using the plurality of symbols entered by a user of the second computing device.

Methods for determining the representation of time-dependent attributes stored in a database and extracting data according to the representation of the time-dependent attributes are described. In some cases, a time-dependent attribute may comprise a time scale varying attribute (TSV) in which a sum may be computed for any date range. In some embodiments, a time-dependent attribute may be represented as a Character Large Object (CLOB) that encodes information about the time-dependent attribute in a text string and may be accessed by table functions. Alternatively, some time-dependent attributes may also be represented as Binary Large Objects (BLOBs) that are used to populate timeslicing tables. Upon receiving a query for data pertaining to a stored time-dependent attribute, a system identifies whether the stored time-dependent attribute is represented as a CLOB or a BLOB, and generates the queried data in a manner dependent on the representation of the time-dependent attribute.
