SMS Sender Registration Scheme

Starting from 11 May 2025, HKEX will start using a Registered SMS Sender ID “#HKEX” to send SMS OTP to local subscribers of mobile services in Hong Kong. For details, please refer to the FAQ section “Security Token - SMS One-time Password (SMS OTP)” 

Access ESS using SMS OTP

HKEX has recently received reports from certain ESS users (non-local mobile 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.
