Why has the Government of Canada introduced GCKey?

The GCKey service was introduced as 1 of 2 options to replace the Access Key service. GCKey is a service managed by the Government of Canada that uses electronic credentials (usernames and passwords) so you can access federal government services online. The GCKey service can be used for those who do not have online banking credentials or choose not to use them with Sign-In Partner (Interac^® sign-in service).
