Mobile Banking App

We’re working on a new app that will replace your existing mobile banking app. The new Bank of Ireland mobile app will have increased functionality and stronger security and will work on both phone and tablet devices.

Our 365 online desktop banking service will also be upgraded, with improvements in how it looks, feels and operates.

What do you need to do now?

To get ready for the switch over to our new app, there’s one key step:

Make sure that you have your correct mobile phone number registered to your online banking profile.

Here’s how:

  1. Login into 365online and choose “Manage Accounts”

    If you can’t remember your User ID when logging in, login to your mobile banking app and choose “More” – your User ID will appear at the top of the screen. Alternatively, text “User” to 50365 and we’ll text your User ID back to you.

  2. Go to “Amend My Mobile Phone Registered for Security Codes”
  3. Check that we have your correct mobile phone number

    If in any doubt – re-register your mobile phone on the above page by entering and confirming your number. You will receive a new activation code in the post in 5 days. If your number is already registered, you are not required to do anything further.

  4. When you receive your activation code in the post

    Login to 365online, go to “Amend my mobile phone registered for security codes” and input the activation code. Once this is done, you are ready for download of the new app once it becomes available.

  5. Please only use this code to activate your mobile number on Banking 365. Never share this code with anyone, for any reason.

How will the new app differ from the current one?

Apart from a range of new features, the app will come with enhanced security known as Strong Customer Authentication (SCA). We’re also adding new fraud prevention measures.

How does Strong Customer Authentication (SCA) work?

Strong Customer Authentication will apply when you access mobile banking or make certain payments online. We may send you notifications to ask you to confirm that you have authorised payments, logged in or wish to make changes to your accounts

Authentication will be based on the following:

Something you own e.g. smartphone


Something you know e.g. PIN

Not registered for online banking?

Getting set up on 365 online is now easier than ever before. When you call us, we will confirm your identity with three simple security questions relating to you and your account, and get your 365 online account set up and activated all in one simple phone call.
