    Secure Call Authentication

    With impersonation scams on the rise, it can sometimes be difficult to tell whether a call is genuinely from UOB.

    To give you greater peace of mind, Secure Call Authentication allows you to authenticate scam and fraud prevention calls made by UOB representatives directly through your UOB TMRW from 18 May 2026 - so you know the call is truly from UOB.

    To use this feature, please ensure that you have enabled your digital token in UOB TMRW, which will be used to authenticate the call securely.

    How does this work?

    Step 1 –If you’ve received a call on scam and fraud prevention from a UOB representative, he/she will trigger an authentication request to you via Push notification on UOB TMRW.
    Step 2 –‘Approve’ or ‘Reject’ the request. To approve, proceed to enter your digital token code.
    Step 3 –Once you have approved the request and completed the authentication, return to the call with our UOB representative.

      Enhanced real-time fraud surveillance to safeguard your transactions

      To better safeguard your accounts against fast‑evolving scams, UOB has enhanced our real‑time fraud detection measures as required under the Monetary Authority of Singapore’s (MAS) and Infocomm Media Development Authority’s (IMDA) Guidelines on Shared Responsibility Framework (SRF).

      Transactions* may be held for at least 24 hours. This safeguard gives you extra time to review or cancel a transaction if unauthorised.

      If you are unsure about a held transaction, you can cancel it before the funds are processed.

      • For UOB TMRW, go to the Accounts tab > select relevant account > ‘On Hold’ transaction > Cancel
      • For Personal Internet Banking, select the relevant account > Accounts Summary > Transactions On Hold > select the transaction > Actions > Cancel

      If you suspect fraud, call our 24/7 Fraud Hotline at 6255 0160 and press “1” to report a case.

      For assistance on held transactions, please call us at 6355 1122.

      For more information on the SRF, please refer to the MAS website.

      *This excludes recurring standing instructions, recurring GIRO/ eGIRO deductions, bill payments to billing organizations maintained by the Bank, debit card transactions, and intrabank transfers to your other account(s) within the Bank.

              Our security best practices and policies
              chevron
              • UOB Group Internet Banking Privacy Practices

                • The United Overseas Bank Group (UOB Group) is committed to maintaining best Privacy Practices to create, as far as possible, a secure Internet banking environment for our customers. We encourage our customers to similarly observe best practices that are within their control.

                  Our best practices include:

                  1. Collection Of Customer Information
                    We will not make unsolicited requests for customer information through email or the telephone, unless customers initiate contact with us. We will use any information collected as minimally as possible, mainly to assist us in customising and delivering services and products that are of interest to our customers. Under no circumstances will we ask customers to reveal their Personal Identification Numbers (PINs) or Passwords.

                  2. Handling Of Customer Information
                    We have established strict confidentiality standards for safeguarding information on our customers.

                  3. Disclosure Of Customer Information
                    Unless we have the customer's agreement or are required by law, we will not disclose customer information to external parties.

                  4. Compliance By External Parties
                    External parties who, in the course of providing support services to us, may come into contact with customer information, are required to observe our privacy standards.

              • UOB Group Internet Security Technology

                • We understand customer concerns for security when they transact over the Internet. We have therefore built a security system for online banking that safeguards the confidentiality of our customers' account information and their banking transactions.

                  We employ several different methods to protect customers' account and personal information:

                  1. Firewalls
                    We have multiple levels of firewalls in place between our internal computer systems and the Internet.

                  2. Encryption
                    Strong encryption protects customer information as it travels over the Internet. We use the 128-bit Secure Sockets Layer (SSL) encryption to protect the confidentiality of customers' account details and transaction data. This 128-bit SSL encryption is the commercially available security protocol for encrypting or scrambling data transmitted over the Internet. It is also currently recognised internationally to be of the highest standard in encryption technology commercially available and is generally adopted by banks in Singapore and financial institutions worldwide.

                  3. Username and Password
                    Only your valid Username and Password which identify you uniquely, will allow you to log in to our secure website(s). This ensures that messages from authorised users only are admitted into our secure site(s).

                  4. Technology Devices
                    UOB may, from time to time, issue Devices and/or establish security procedures that you may need to execute in order to use certain UOB Internet Banking services related to the Devices.

                    You may use the Devices (whether or not in conjunction with the Username and/or Password or otherwise):
                    • To initiate, effect, perform and/or dispatch any instruction or any communication to UOB;
                    • To obtain or utilise any service that may be offered or made available by UOB through the Website or UOB Internet Banking service;
                    • To access and obtain information as may be permitted by UOB (whether relating to your Account(s), service or otherwise); and
                    • To effect any transaction with UOB which may be made available by UOB, subject to the terms of this Agreement and to other restrictions, limitations, terms and conditions of UOB then applicable


                  5. Automatic Log Out
                    As an additional security measure, our system may log you out of your Internet banking session after a period of inactivity

                  We are committed to monitoring our Internet security system constantly for potential situations that could compromise the security or the privacy of our customers and to exploring new technology continually to enhance our Internet security system.
