Mastercard SecureCode protects your credit card against unauthorised use when you shop online at participating retailers.

You’ll see this logo on the participating retailer’s website:

It’s free to use the Mastercard SecureCode service. 

No, all cards are automatically registered for the service. All you need to do is make sure your mobile number is registered with us, because we may send you a one time passcode (OTP) to complete the online transaction.

The authorised user must also register their mobile number with us to use the Mastercard SecureCode service.

OTP is a 'one time passcode'. It’s a random number we send to your mobile number registered with us. When you enter it, it allows the Bank to identify you and ensures that a greater level of security is applied to your transaction.  

When you use your card online with a retailer who uses the Mastercard SecureCode service, a Mastercard SecureCode screen will appear, if authentication is required. You will be asked for the last four digits of your mobile number. Then another screen will appear asking you to enter the OTP we sent to you by text message. This confirms your identity. When the transaction goes ahead you are accepting our Mastercard SecureCode Terms and Conditions.

The sender ID on the text message from Allied Irish Bank (GB) will be AIB GB.  We will not ask you for account numbers or PIN numbers. We will only provide the OTP in the text message. We will not request you to respond to the text message.

Here is a sample of the text we may send you. It will not identify you or your card:

AIB GB: For your Mastercard SecureCode transaction at Amazon Digital for GBP 000000000, please use this One Time Code; 12345678 within five minutes. Thank you.

It’s temporary and designed to be used for one transaction and lasts for five minutes.

If you do not receive your OTP within five minutes, click on the 'Send new one time passcode' link on the Mastercard SecureCode screen and a new OTP will be sent. 

You’ll have 3 attempts to click on the 'Send new one time passcode' link. Once you have clicked on the link 3 times, then the link will be disabled. If this occurs, please contact us at 028 9032 8907.

The registered mobile number is a mobile number which we have on record for you. We will show the last 4 digits of your mobile number on the Mastercard SecureCode screen when we send you the OTP. You may not be able to proceed with your online purchase if we do not have a valid mobile number registered for you. You can register your mobile number with us, by calling us on 028 9032 8907.

This confirms your mobile number and that we are sending the OTP to the correct mobile number.
