Taiwan Business Bank Log In is available through TBB Personal Online Banking, the Taiwan Business Bank mobile app, and separate corporate banking services. Taiwan Business Bank is an active domestic bank supervised in Taiwan, not Taiwan Cooperative Bank or Bank of Taiwan.
Personal customers should start from TBB’s current official website and choose Internet Banking. Business customers use the corporate route and company-issued permissions. Do not enter credentials on a page simply because it contains the words Taiwan and bank.
How to Log In
For Taiwan Business Bank Log In, choose the channel that matches the profile. Personal Online Banking uses the current user name and user password. The mobile app is for eligible personal Internet Banking customers, while corporate users have separate administrator and approval controls.
Personal Online Banking
- Type Taiwan Business Bank into your browser and open the current official TBB website yourself.
- Choose Internet Banking and confirm the page says Personal Online Banking.
- Select English when needed before entering information.
- Enter the current user name and user password.
- Complete any SMS, financial-card, or device verification requested for the action you started.
- Review balances and recent activity before making a transfer or payment.
- Log out when finished and close the session on a shared computer.
TBB mobile banking app
- Install or open the official Taiwan Business Bank mobile banking app from the current store listing.
- Confirm that the publisher is Taiwan Business Bank Co., Ltd.
- Use the personal Internet Banking profile registered with the bank.
- Complete device binding and verification only for your own phone.
- Set biometric or pattern login only after a normal login succeeds.
- Check the beneficiary name and transaction details before approving a transfer.
- Review the app login history and alerts after any unexpected event.
Choose Personal or Corporate Banking
Taiwan’s Financial Supervisory Commission lists Taiwan Business Bank as a domestic banking institution, and the bank’s English site describes both general network banking and corporate network banking. These are not interchangeable profiles. A personal deposit customer should not try corporate credentials, and a company user should follow the administrator and transaction-approval process assigned by the business.
TBB’s corporate service may use an administrator sign-in password, certificates, mobile push approval, or an I-KEY depending on the company’s setup. The corporate app and web portal also share failure counts for the same user. Contact the company administrator before asking the bank to reset an ordinary employee’s permissions.
- Personal customer: use Personal Online Banking or the personal mobile app.
- Corporate customer: use the corporate Internet Banking and corporate app route.
- Company administrator: controls user setup and may need to reset or reassign access.
- Transaction approver: use only the certificate, push approval, or I-KEY assigned by the company.
- Do not mix personal and corporate usernames or passwords.
- Call TBB when the correct channel is unclear or the administrator cannot resolve it.
First Login, Enrollment, and Device Binding
TBB’s current English instructions say the first personal login requires the old user password and a new user password. After the change is confirmed, return to the login page and sign in with the new password. Save the change only through the live TBB session you opened yourself.
The personal mobile app requires an eligible personal Internet Banking customer, a registered mobile number and email, and an account that meets the bank’s device-binding requirements. Some online enrollment or reset routes use SMS verification together with a chip financial card. If those tools are unavailable, ask TBB whether a branch reset is required.
- Use the temporary or old password only on the official first-login screen.
- Create the new user password when TBB prompts for it.
- Return to the login page and test the new password once.
- Keep the bank’s registered mobile number and email current.
- Bind only a phone you control and review trusted devices regularly.
- Use a branch when identity, chip-card, or contact details cannot be verified online.
Reset the User Name or Password Safely
TBB’s Personal Online Banking help provides a Forgot User name/Password path. The documented reset process can request identity information, an SMS verification code, and insertion of the bank’s chip financial card into a compatible reader before confirmation. Follow only the fields shown in the current official session.
Do not share the SMS code, chip-card PIN, user password, or a remote view of the computer with someone who contacts you. If the registered phone is no longer available, the chip card is missing, the reader does not work, or repeated attempts have stopped access, call the 24-hour service center or visit a branch.
- Choose Forgot User name/Password from the current personal banking page.
- Select the reset option that matches the missing credential.
- Receive the SMS code only on the number registered with TBB.
- Use the chip financial card and reader only when the official process requests them.
- Stop after repeated rejection instead of risking a longer lockout.
- Call 0800-01-7171 or 02-2357-7171 when self-service recovery cannot finish.
Known Issues & Common Problems
Wrong Taiwan bank: Taiwan Business Bank, Taiwan Cooperative Bank, and Bank of Taiwan are separate institutions. Confirm TBB before entering credentials.
Personal or corporate route mismatch: Use the channel assigned to the profile. Corporate users may need their company administrator.
First-login password fails: Use the old password once, create the required new password, then return to the login page and test it.
SMS code does not arrive: Check the registered phone and signal, then call TBB rather than requesting codes repeatedly.
Chip card or reader unavailable: The online reset may require both. Ask TBB whether recovery must be completed at a branch.
Profile or transaction locked: Stop guessing and contact the service center or company administrator before another attempt.
Taiwan Business Bank Log In problems usually become clearer after separating the institution, channel, credential, SMS delivery, chip-card verification, and account or transaction status. Record the exact message and last successful step before contacting support.
Troubleshooting Tips
- Confirm that the institution is Taiwan Business Bank, abbreviated TBB.
- Start from the bank’s current official website.
- Choose Personal Online Banking or corporate banking correctly.
- Check Caps Lock, keyboard language, and saved-password autofill once.
- Use Forgot User name/Password instead of repeated guesses.
- Confirm the registered mobile number can receive the SMS code.
- Use the chip financial card and reader only in the official reset flow.
- Ask the company administrator about corporate user permissions.
- Record the message, time, device, and last successful step.
- Call the 24-hour service center when access or a transaction remains unresolved.
A rejected password is an access issue. A missing SMS is a delivery issue. A failed chip-card step is a verification issue. A corporate approval problem may belong to the company administrator. Keeping those separate helps TBB route the case correctly.
Security Tips
- Type the current TBB address yourself rather than opening an unexpected banking link.
- Confirm the bank name and secure connection before entering information.
- Never share a user password, SMS code, chip-card PIN, certificate password, or I-KEY approval.
- Bind only a mobile device you control and review login records.
- Use the mobile app’s transfer locks and limits when appropriate.
- Check the displayed beneficiary name and amount before approval.
- Do not allow an unknown caller to view or control the login device.
- Call TBB immediately for an unknown login, transfer, lost card, or exposed credential.
A real bank message never makes an unexpected request safe by itself. End the interaction, open TBB’s site or app independently, and contact the 24-hour service center using the published number.
Contact Customer Service
- 24-hour customer service in Taiwan: 0800-01-7171.
- 24-hour customer service from mobile or other locations: 02-2357-7171.
- Urgent lost card or passbook: call the 24-hour service center immediately.
- Corporate access: contact the company’s system administrator first, then TBB when bank-side help is needed.
- Branch help: use TBB’s current branch locator for identity, chip-card, contact-detail, or password-reset work.
- Head office: 30 Tacheng Street, Datong District, Taipei City 103, Taiwan.
Tell support whether the problem affects personal or corporate banking, web or app, login or transaction approval, and whether SMS or chip-card verification completed. Never provide a password or one-time code to an agent through ordinary email or chat.
