"At Westpac, we are continually striving to provide the highest quality service and security to help support our Online Banking customers.
From the end of May 2018, we will be removing the keypad from the online sign-in screen and replacing it with an open text box, which allows you to type in your Customer ID and password.
...
Security Guarantee.
We assure you that using the open text box to enter your sign-in details carries the same high level of security ..."
Passwords remained fixed at 6 characters however.
