  • Q2.
    What authentication methods do GovHK online services use?
    Ans

    Different GovHK online services may apply different authentication methods as appropriate for the levels of security required by their transactions with the users. Possible authentication methods include:

    • user ID and password;
    • digital certificate stored on a floppy disk, hard disk or USB flash drive, whereby user will be required to enter a password and specify where the certificate is stored; or
    • the Hongkong Post e-Cert stored on a smart identity card, whereby the system may prompt for the e-Cert password during the authentication process.

    Each online service will specify the applicable authentication method(s). Please refer to the FAQs of individual service for details. For general information about digital certificates and authentication, please refer to the following FAQs section.

You need to right click each of the links as highlighted in Q3 and select “Save Link As” to store the certificate file to your hard disk.
