External Credential Service for Protected Web Server
The PWS program allows NRC license holders, applicants, and authorized stakeholders to voluntarily submit and share suspicious activity reports and other security data.
This system consists of a secure, Web-based database. In order to access this application, a user must obtain a digital credential. This credential, in the form of a One Time Password (OTP), allows the PWS system to uniquely identify each user. The process of obtaining the digital credential is called credentialing.
For more details on the credentialing process, please visit Credentialing Overview.
If you have any questions or concerns, please send your inquiry to the PWS help desk at pws.mail@nrc.gov.
