Notice

HKEX has recently received reports from certain ESS users that they are unable to receive One-Time Passcode (OTP) via mobile SMS for ESS logon. Whilst HKEX is checking with its service providers on the alleged non-delivery of SMS OTP, ESS users are advised to use the software token “MobilePASS+” for accessing the ESS.  Should you have any enquiries relating to the above, please call our ESS hotline at (+852) 2840 3460.
