Secure Log In
We have made some changes to how you will log into your AIB Personal Banking Services (AIB Mobile App, Internet Banking, kiosk and Phone Banking). We are now asking you to enter all five digits of your Personal Access Code (PAC) when you log into our online channels, and again when we ask you for your PAC at certain times in the app.

This change is part of a security update and it will ensure your online banking has an extra layer of security. You will also notice a new look when you log into your Internet Banking and you will notice some additional screens when you are logging into your Mobile App.

In the past we said we would not ask for all five digits, but we have now decided that it is the easiest way for you to log in with extra layers of security we have in place.

Further information is available here

Please remember: we will never contact you by email, text or phone asking for a code. These codes are the way to make money leave your account. Never share them with anyone.

Secure log in – Our Internet and Mobile services employ a secure login process. Remember, it is important that you never disclose your personal log in information to a third party.

Logging in to the AIB Mobile Banking App
Once you have registered for Phone and Internet Banking, you will need to complete the following steps:
1. Find and install the AIB Mobile app from the Apple App store or Google Play store on your mobile phone.
2. Open the app and log in with your 8 digit Registration Number and Personal Access Code (PAC).
3. Complete the one time set up on the AIB Mobile App, we will send you a one-time code as part of this setup.
After you have completed the one time setup, you can then log into the app anytime by just using your PAC or by using Face ID, Touch ID or finger print authentication for every other log in.

You can unregister your Registration Number from your phone by selecting Unregister Device in the Services / App Settings option in the app or by calling a Customer Service Advisor on +353 1 77 12 424). Our operation hours are 09:00 to 17:00 Monday to Sunday.
Encrypted Website

To ensure you can access your accounts over the Internet with the utmost confidence, we use the highest levels of industry standard security. As part of this security our connections use TLS1.2, the connection is encrypted using the Advanced Encryption Standard (AES) and keys are exchanged via Diffie-Hellman ciphers.
Auto Time-Out

This feature aims to protect you against unauthorised access.

AIB Internet Banking will automatically log you out after 5 minutes of inactivity. However 60 seconds before you are timed out due to inactivity, you will see a prompt and will have the option to remain logged in.

AIB Mobile Banking will automatically log you out after 4 minutes of inactivity. You must be actively browsing to stay connected (i.e. switching between accounts). However 30 seconds before you are timed out due to inactivity, you will see a prompt and will have the option to remain logged in.

Please note: Scrolling through statements does not count as active browsing. Active browsing is when you are clicking on links within the website, i.e. selecting a different tab on the left of the screen or switching between accounts.
Time and Date Stamp

Each time you log in to Internet Banking we will display the details of your last log in. This is an additional security measure that we have taken to ensure that you can see if someone has fraudulently accessed your accounts online.

The details shown are the day, date and time on which you last accessed the service. It is important that you check your last log in every time you log in to Internet Banking. It will be displayed in the top navigation bar. If you are suspicious of the last log in shown and do not recall logging into Internet or Mobile Banking on that date, please contact our Customer Service Advisers for assistance.
AIB Card Reader

The AIB Card Reader offers extended security which enables us to offer customers an extensive range of services through AIB Phone & Internet Banking.
