Managing your login security

Keeping your internet banking credentials updated is a routine part of maintaining your financial security. If you suspect your password has been compromised, or if you simply want to refresh your security settings, you can manage this directly through the Suncorp Internet Banking portal or the mobile app.

You’ll generally find that the process relies on verifying your identity through your registered mobile number. Before starting, ensure you have your phone nearby, as the system will likely send a secure verification code to confirm that you are the one making the changes.

Steps to update your password

To change your password, you will need to be logged into your account. If you cannot log in, use the 'Forgot Password' link on the login page instead of the steps below.

  1. Log In: Access your account through the Suncorp website or the official mobile app.
  2. Access Settings: Navigate to the 'Settings' or 'Profile' menu. This is typically located in the top right corner of the web interface or under the 'More' tab in the app.
  3. Security Options: Select the 'Security' or 'Login Details' tab to view your current settings.
  4. Update Password: Choose the option to change your password. You will be prompted to enter your current password before creating a new, secure one.
  5. Confirm Changes: Follow the on-screen prompts, which may include an SMS verification code sent to your registered mobile number, to finalise the update.

Troubleshooting common issues

MFA / Login Issues
Cause: The verification code may have expired or was not received due to network delays. Fix: Request a new code after waiting a few minutes. Fallback: If you continue to experience delays, call Suncorp customer support to verify your contact details.

Browser or App Errors
Cause: Stored cache or cookies in your browser can occasionally interfere with the banking portal. Fix: Clear your browser cache or try using an 'Incognito' window. Fallback: If the site remains unresponsive, contact support to confirm if there is a known service outage.

Locked Account / ID Access
Cause: Entering incorrect details multiple times often triggers a security lockout to protect your account. Fix: Wait 24 hours for the system to automatically reset. Fallback: If you need immediate access, you must contact Suncorp directly to verify your identity and have the lock removed.

Pro-Tip: Using a password manager is a reliable way to keep track of your credentials without needing to reuse the same password across multiple websites. This improves your security posture significantly, as you can generate long, unique passphrases that the manager remembers for you, reducing the likelihood of password-related lockouts.

Frequently Asked Questions

Q: Why has my account been locked after trying to change my password?
This typically happens if the system detects too many failed attempts in a short timeframe, which is a safety mechanism to prevent unauthorised access. While this can be frustrating, it is designed to protect your funds. You will usually need to wait 24 hours for the temporary block to clear, but if you have an urgent payment to make, call the bank to verify your identity and request a manual reset.

Q: What if I do not receive the SMS code to update my details?
If the SMS code does not arrive, it is often due to a poor mobile signal or a delay with your telecommunications provider. First, ensure your phone has a stable connection, then try requesting the code again. If you have recently changed your phone number, the code will still be sent to your old number. In this case, you will need to call Suncorp to update your contact details before you can proceed with the password change.

Q: How often should I change my online banking password?
There is no fixed requirement to change your password on a set schedule, provided you use a strong, unique passphrase. However, if you suspect that your login details have been shared or if you have logged into your bank from a public computer, it is good practice to update your password immediately. If you decide to update it, choose something unique that you do not use for any other service.
