Open24 Web Authentication

Authorising Third Party Provider (TPP) Services

When completing a transaction with your Third Party Provider, for security reasons, we may ask you to authorise the request and complete authentication.

Here you can see step-by-step guides on what to expect when authenticating these TPP requests via Open 24 web. There are two types of authentication that you may experience.

Types of authentication methods

I am an app user

• You will receive a push notification to your registered device and will be asked to authenticate by entering 3 digits from your 6 digit Open24/Business24 Personal Access Number (PAN)

I am a non app user

• You will be asked to authenticate by entering 3 digits from your 6 digit Open24/Business24 Personal Access Number (PAN)
• You will also be asked to confirm the One Time Passcode sent to your registered mobile number

Card Based Payment Instrument Issuer (CBPII)

A CBPII can make an enquiry to PTSB to see if you have sufficient funds in your payment account. They will not be given a balance of your account but just a ‘Yes’ for funds available or a ‘No’ for funds not available.
