What is ‘Link and Switch’?
Link and Switch is a feature in NAB Internet Banking that allows you to securely link up to 20 of your most recently used eligible NAB IDs to a single ID of your choosing.
This means you’ll only need to log into NAB Internet Banking once, using your main ID, and you’ll be able to switch between all the NAB IDs you’ve chosen to link, without logging in and out again.
Link and Switch is only available when you use a web browser to log into NAB Internet Banking and not the NAB app.
Please note:
- You can only link NAB IDs that have been registered for NAB Internet Banking.
- If you need to make any changes to your personal details, they will not copy over to the linked IDs. You will need to update each linked ID separately.
