CITIBANK ONLINE - CBOL SECURITY

Secured online banking.

Secured online banking.

In our continuous effort to make Citibank Online a secured banking environment for you, we have introduced the new Online Security Device (OSD).

OSD

The new OSD is a personal device that enables you to generate a single-use random set of numbers during online transactions. It offers two security features: One-Time PIN (OTP) and Transaction Signing.

Greater Online Security

If you are holding on to the existing OSD (oval-shaped device), you will still be able to use that to access Citibank Online services except those that require Transaction Signing.

Or

If you wish to request for a new OSD, simply follow the steps to request for an OSD via Citibank Online.

No, the new OSD has already been pre-registered for you. If you are still holding on to the old OSD (oval shaped device), please request for the new OSD to be mailed to you.

The new OSD provides Citibank Online with Transaction Signing, which is an additional authentication capability. It uses transaction-specific information (Challenge Code) to generate a secure Transaction Authorization Code (TAC).

TAC is required when performing certain online transactions, including the following:

  • Adding of Payee for Transfer & Payment
  • High Value Transfer & Payment
  • Telegraphic Transfer
  • Change of E-mail Address

No. The old OSD will be disabled immediately once you start using the new OSD. You do not need to return the old OSD to the bank and can dispose of it safely.

To display the OTP or TAC, you must press and hold the respective OTP button or TAC button. If nothing is displayed on the OSD screen, please call our 24-Hour CitiPhone Banking at +65 6224 5757+65 6224 5757.

You should inform us by contacting our 24-Hour CitiPhone Banking at

+65 6224 5757+65 6224 5757 to deactivate your lost or stolen OSD immediately.

You should request for a replacement OSD via Citibank Online.

The OSD is battery-powered with a lifespan between three to five years, depending on the frequency of the usage. Please request for a replacement OSD via Citibank Online.

  • Change of E-mail Address

OTP sent to your mobile phone via SMS or generated by your OSD is valid for 2 minutes. For OTP received via SMS, only the latest SMS will be valid.

If you are using the OSD and exceed 2 minutes, you will need to generate a new OTP again.

OTP generated from the OSD synchronizes with our servers each time you login. OSDs not utilized for long periods of time will be made to go out of sync with our servers. If you encounter errors while login in with a correct OTP generated from your OSD, please contact your Relationship Manager or call our 24-Hour CitiPhone Banking at +65 6224 5757+65 6224 5757 to re-synchronize your OSD.

Upon successful update of your mobile number, please allow 3 - 5 working days for your number to be effective and ready to receive OTP.
