NAB Digital Banking 3

Question 1

Which multi-factor authentication method does NAB most commonly use when customers perform sensitive transactions online?

Accepted Answer

A one-time password (OTP) sent via SMS to the registered mobile number

Answer

NAB sends a one-time SMS code to the customer's registered mobile as a second factor to verify high-risk actions like adding new payees.

Question 2

If a NAB customer suspects their internet banking credentials have been stolen, what is the FIRST action they should take?

Accepted Answer

Immediately change their password and call NAB to report the compromise

Answer

Changing the password immediately limits the attacker's access window, and reporting to NAB allows the bank to flag the account and investigate unauthorized activity.

Question 3

NAB's card lock feature in the mobile app allows customers to:

Accepted Answer

Temporarily freeze a card to prevent all transactions

Answer

The card lock feature lets customers instantly freeze their debit or credit card to stop all transactions, which can be unlocked again if the card is found.

Question 4

NAB will NEVER ask customers to provide which information via email, SMS, or phone call?

Accepted Answer

Their full internet banking password or PIN

Answer

NAB's security policy states the bank will never ask for a full password or PIN through any channel — requests for this information are a sign of fraud.

Question 5

Which biometric authentication option does the NAB mobile app support on compatible devices?

Accepted Answer

Fingerprint and Face ID to log into the app

Answer

NAB's app supports fingerprint (Touch ID) and facial recognition (Face ID) on compatible iOS and Android devices as a convenient and secure login method.
