To access BOC Singapore Internet Banking, navigate to the official Bank of China Singapore portal at https://www.bankofchina.com/sg, select Personal Online Banking or Corporate Online Banking, and authenticate using your Username, Password, and a 6-digit One-Time Password (OTP) from your BOC eToken. Designed for retail account holders, cross-border expatriates, and corporate treasury teams in Singapore, the platform connects local SGD and multi-currency accounts to Bank of China's global clearing network. Because BOC operates its regional portals on its centralized boc.cn infrastructure, logging in requires specific local security controls—including the browser-based Safe Control encryption plugin and hardware Transaction Signing for high-value transfers. Below is the complete technical walkthrough to configure your browser, bind your security token, and resolve authentication lockouts.

Required Credentials, Security Applet & eToken Setup
- Active Qualifying BOC Account: You must maintain at least one active Savings Account, Current Account, Time Deposit, Loan Account, or Credit/ATM Card with Bank of China Limited, Singapore Branch.
- Login Username & Pin Mailer Password: New enrollees receive a temporary username and initial password via a physical Pin Mailer or on-the-spot branch issuance, which must be customized upon first sign-in.
- BOC eToken or Mobile Token: A physical hardware security device (or activated digital Mobile Token inside the BOC Mobile Banking app) capable of generating 60-second dynamic Login OTPs and challenge-response Transaction Signing Passwords (TSP).
- Safe Control Browser Applet: Desktop browsers (Microsoft Edge, Google Chrome, or Safari) must have the official BOC 'Safe Control' security control plugin installed to permit keystroke encryption inside the password field.
How to Sign In to BOC Singapore Online Banking
- Step 1: Open a secure desktop web browser and navigate directly to the official Bank of China Singapore gateway at https://www.bankofchina.com/sg. Locate the login module on the right side of the homepage and click either Personal Online Banking Login or Corporate Online Banking Login.
- Step 2: Acknowledge the Electronic Banking Services notice to load the regional authentication screen (hosted on the official boc.cn global banking infrastructure). If logging in on a computer for the first time, click Click to install Safe Control inside the password box, run the downloaded installer, and refresh your browser.
- Step 3: First-time users who received a hardware token via post displaying a 12-digit code must first click Activate and bind eToken, enter the 12-digit activation string, press the Login OTP button on the device, and click Bind. Returning users whose device displays 'Thank you for using BOC eToken' can proceed directly to the main sign-in fields.
- Step 4: Type your registered Username and encrypted Password into the respective input boxes. Press the power/OTP button on your BOC eToken (or open your Mobile Token or SMS OTP message) and enter the 6-digit One-Time Password (OTP) before the 60-second timer expires.
- Step 5: Enter the alphanumeric Verification Code (CAPTCHA) displayed on screen and click Login to load your Accounts Overview dashboard, where you can verify your SGD and foreign currency balances.
PayNow Transfers, Remittances & Global Account Tools
- PayNow & FAST Local Transfers: Link your Singapore NRIC/FIN or local mobile number under PayNow > Registration Management to send and receive real-time SGD funds 24/7. Transfers up to SGD 1,000 daily can be executed rapidly without requiring an OTP challenge.
- Cross-Border Remittance & RMB Pre-Settlement: Execute international telegraphic transfers, track cross-border wire statuses via BOC Global Payments Innovation (GPI), and perform direct Renminbi (RMB) pre-settlement and multi-currency exchanges across 38 supported currencies.
- Hardware Transaction Signing (High-Risk Security): Protect critical account changes—such as adding new third-party payees, raising transfer limits, or sending wires above the default SGD 10,000 threshold—using challenge-response Transaction Signing Passwords (TSP) generated on your eToken.
- Global Account Management & Term Deposits: Open or roll over Term Deposit accounts online, link international BOC accounts under Global Service for consolidated asset viewing, download 12-month transaction histories, and manage Credit Card statements and bill payments.
Fixing Safe Control Applet Errors & eToken Sync Failures
⚠️ Password Field Locked or 'Click to Install Safe Control' Appears Repeatedly
Cause: Bank of China's login portal blocks standard keyboard input into the password field until its anti-keylogger Safe Control plugin is active, or your browser's security settings are blocking the plugin from running.
Solution: Click the download link inside the password field, close all open browser windows, and run the installer as an Administrator. After installation, relaunch your browser, allow the plugin extension to run on boc.cn/bankofchina.com, or switch to Compatibility View if using Microsoft Edge.
⚠️ Concurrent Session Conflict Between Desktop and Mobile App
Cause: BOC Singapore's security architecture strictly prohibits simultaneous active sessions across Personal Online Banking (desktop) and the BOC Mobile Banking App.
Solution: Completely log out of the BOC Mobile Banking App on your smartphone (do not simply minimize the app in the background) and wait 60 seconds before attempting to sign in on your desktop browser.
⚠️ eToken Dynamic 6-Digit OTP Rejected During Login
Cause: The 60-second internal clock on the physical eToken has drifted out of sync with the bank's authentication server, or the same OTP was entered twice.
Solution: Wait for the current code on your eToken screen to clear, press the 'Login OTP' button once to generate a fresh 6-digit sequence, and submit it immediately. If the new code still fails, call the 24-hour hotline at 1800 669 5566 to resynchronize your token serial number.
⚠️ Online Banking Username or Password Locked After Failed Attempts
Cause: Entering an incorrect static password or expired eToken code multiple consecutive times triggers an automatic security freeze on your electronic banking profile.
Solution: If you only forgot your password, check if self-service reset is available on the login screen; otherwise, because BOC Singapore requires strict identity verification for locked profiles or lost Pin Mailers, visit any BOC Singapore branch in person with your NRIC/Passport to reissue your credentials on the spot.
Two-Factor Authentication & Anti-Phishing Protocols
- 🔒 Verify the Official Domain Transition: Always start your session at https://www.bankofchina.com/sg. When clicking the login button, the portal legitimately routes to Bank of China's global banking platform (https://ibs.boc.cn or www.boc.cn). Inspect your browser's SSL padlock to ensure the certificate belongs to Bank of China Limited.
- 🔒 Never Share Transaction Signing Codes: A standard Login OTP only grants account viewing access, whereas a Transaction Signing Password (TSP) authorizes outgoing money transfers and new payee additions. BOC staff will never call or SMS you to ask for a 6-digit eToken code.
- 🔒 Configure Custom Outgoing SMS Alerts: Navigate to Service Setting inside your online dashboard to customize your transaction notification thresholds. You can set SMS or push alerts as low as S$0.01 so any unauthorized activity triggers an instant warning on your mobile phone.
- 🔒 Protect and Replace Lost eTokens Immediately: If your physical eToken is misplaced or stolen, call 1800 669 5566 immediately to suspend online access. Once a replacement eToken is issued and activated at a branch (a SGD 20 replacement fee plus GST applies for lost devices), your old token is permanently deactivated.

Frequently Asked Questions
Q: How do I apply for BOC Singapore Internet Banking for the first time?
If you hold an active savings, current, time deposit, or card account with BOC Singapore, visit any local Bank of China branch with your NRIC or Passport. Your online banking username, temporary Pin Mailer password, and physical eToken will be issued on the spot so you can log in immediately.
Q: Can I access my account from a smartphone app, and do I still need my eToken?
Yes, you can download the official Bank of China Mobile Banking app from the Apple App Store or Google Play Store. However, you must first be a registered Personal Online Banking user, and you will still need your eToken (or registered SMS OTP / Mobile Token) to authenticate transfers and logins.
Q: Why can't I activate my new eToken on the BOC Mobile Banking app?
Initial one-time activation and binding for a mailed eToken displaying a 12-digit activation code can only be completed on a desktop computer via the Personal Online Banking web portal. Once bound on a PC, the eToken will work seamlessly across both desktop and mobile banking.
Q: What is the difference between Login OTP and Transaction Signing on the eToken?
Pressing the Login OTP button generates a random 6-digit code that refreshes every 60 seconds for signing in. Transaction Signing is used for high-risk actions (like adding a payee or transferring over SGD 10,000) and requires you to key a specific screen challenge code into the eToken to generate a unique Transaction Signing Password (TSP).
Wrap Up
Accessing the BOC Singapore Internet Banking portal is seamless once your desktop browser's Safe Control plugin is installed and your BOC eToken is properly bound. Always initiate your sign-in from https://www.bankofchina.com/sg, keep your desktop and mobile sessions separate to prevent concurrency errors, and rely on hardware Transaction Signing to safeguard high-value remittances. If your token loses synchronization or your password becomes locked, reach out directly to BOC Singapore's 24/7 hotline at 1800 669 5566 for verified assistance.
