What is Strong Customer Authentication (SCA)?

Strong Customer Authentication (SCA) is a security method that we use to help keep your account secure. It's also sometimes known as two-factor authentication (2FA).

We use SCA as an additional security measure when you log into online banking. Once you've entered your customer number and password, we'll send a code to the mobile number you've shared with us, which you'll need to enter into the login screen when prompted.
