Money apps make everyday tasks convenient, but they also hold details you may not want exposed: account access, contact information, purchase history and sometimes identity documents. Good privacy habits do not have to be complicated. A few small checks can reduce avoidable risk while keeping the tools you use practical.
1. Give important accounts unique passwords
Reusing one password across email, banking and shopping accounts means a password exposed in one place may put other accounts at risk. The Office of the Privacy Commissioner recommends long, unique passwords and says a password manager can help you manage them. If an account offers multi-factor authentication (MFA or 2FA), turn it on: it adds another sign-in check beyond the password.
2. Pause before sharing personal details
If an app, caller or website requests information, ask why it is needed, how it will be used and who will see it. A request may be reasonable in one context and unnecessary in another. Check the organisation’s privacy information, and do not feel pressured to provide details you do not understand. If someone calls claiming to represent a bank or agency, you can end the call and contact the organisation using a number from its public website.
3. Check links and sign-in prompts
A message that looks urgent can make it tempting to tap first and think later. If an unexpected email or text asks you to log in, open the official app or type the organisation’s known address yourself instead of following the message link. Never share a one-time sign-in code with someone who contacts you. If a prompt arrives when you were not trying to sign in, treat it as a reason to check the account through a trusted route.
4. Review device and app settings
Check which apps can access your contacts, location, camera or notifications, and switch off permissions that are not needed for the service to work. Keep your phone and apps updated, use a device lock, and sign out of shared devices. Avoid entering sensitive financial information over public Wi-Fi; if you need to take action, use a trusted connection or contact your provider for a safer option.
5. Keep evidence, not exposed card details
Save purchase confirmations and records in a place you can find, but avoid sharing screenshots that reveal full card numbers, account balances, addresses or one-time codes. When asking for help, cover details that are not necessary to solve the issue. If a card or bank detail may have been exposed, contact your bank promptly through its official app or publicly listed phone number and follow its instructions.
The Privacy Commissioner’s guide to protecting personal information covers unique passwords, MFA, privacy settings and questioning requests for information. These steps cannot guarantee that an account will never be compromised, but they make it easier to spot unusual requests and respond through a trusted channel.
Try one small change today: update a reused password, enable MFA on an account that offers it, or review one app’s permissions. A calm, repeatable habit is more useful than trying to fix every setting at once.
FAQs
Should I use the same password for several money accounts?
No. The Privacy Commissioner recommends unique passwords so one exposed password is less likely to unlock other accounts.
What does multi-factor authentication do?
It adds another way to confirm a sign-in, beyond the password, when the service offers it.
What should I do with an unexpected banking link?
Do not use the message link. Open the official app or contact the organisation through a trusted, publicly listed route.
Is it okay to share a sign-in code with a caller?
No. Keep one-time sign-in codes private, and contact the organisation directly if a request seems suspicious.
Should every app have access to my location and contacts?
No. Review permissions and keep only those needed for the service’s features you use.
What if my card or bank details may have been exposed?
Contact your bank promptly using its official app or publicly listed contact details and follow its instructions.
