Starting July 31, 2023, Immigration, Refugee and Citizenship (IRCC) made multi-factor authentication mandatory for all GCKey applicants and representatives to prevent unauthorized access to personal information. The new authentication must be set up for new accounts or for signing into existing accounts. It must be used each time GCKey is used to access the IRCC account but is not required if the Sign-In Partner option is selected. The following accounts require the new IRCC multi-factor authentication: IRCC Secure Account, Authorized Paid Representatives Portal, Employer Portal, Provincial and Territorial Partner Portal, Designated Learning Institutions Portal, Provincial and Territorial Public Health Authority Portal, and the Partner Portal.
