Methods and systems for configuring a main or security processor in a customer premises equipment (CPE) with an encrypted seed for password-of-the-day (PoTD) processing is described. A CPE includes a modem processor, a main processor, and a PoTD component included on the main processor. The main processor receives, via the modem processor from a user device, an access request to the CPE. In response to the access request, the PoTD component accesses an encrypted seed stored on the main processor, generates a PoTD from the encrypted seed, and provides an access response based on comparison of the generated PoTD with a PoTD provided via the user device. A security processor can be used in lieu of the main processor. The PoTD component is then included in the security processor and the encrypted seed is then stored on the security processor.
