Dear Valued Clients,
We are pleased to announce that Multi-Factor Authentication (MFA) will be officially launch on 19 October 2026. This implementation simultaneously elevates the security posture and delivers a better user experience. By activating MFA in your device, it delivers a fast, one-tap approval prompt to your registered primary device to verify user identity during a sign-in attempt.
To ensure a smooth transition, please take note of the following:
1. Valid Email Address Required
All clients must ensure that a valid and accessible email address is registered with us. A One-Time PIN (OTP) will be sent to your email address as part of the Multi- Factor Authentication (MFA) verification.
2. TC Mobile Latest Version
Please ensure your TC Mobile version is aligned with the latest version v3.1.18.
3. TC Mobile Application Compatibility
Please ensure that your TC Mobile app is running on a supported operating system version. The app will only support the latestOS version and the three prior major versions, as listed below:
Note: HarmonyOS compatibility may vary by device.
4. New Password Requirement
Users are encouraged to change their password to at least 9 or more characters and must contain any 3 combinations ofuppercase character, lowercase character, number, or special character from!@#$&%()^*
We strongly encourage all users to update their devices and applications to meet the compatibility requirements to avoid any disruptions. Should you experience any issues or require assistance, please contact our Customer Service Representatives at 03-5567 3030 or WhatApp 010-257 0288.
