PKI Authentication Update

Important update: The deadlines related to authentication change and migration for EFS-Web and Private PAIR are being extended due to technical issues. We will announce the new deadlines when they are determined. Until then, you can still authenticate using either accounts or PKI certificate.

If you have not done so, please create your account, ensure it is opted in to two-step authentication, and use the Migration to link your existing PKI certificate to your account. Registered practitioners should use the Sponsorship Tool to sponsor their support staff to work on their behalf.
