IMB Internet Banking: Login, Sign Up and Mobile App Guide

Logging into your IMB Bank account online shouldn’t require a degree in cryptography. The official login portal at internetbanking.imb.com.au requires your member number and a case-sensitive password, and offers a token OTP for extra security. Whether you’re signing up for the first time or resetting a forgotten password, this guide covers the official steps from IMB Bank directly.

Five key facts about IMB Internet Banking, one pattern: nearly every access point routes through the same member number and password foundation.

How to Log In to IMB Internet Banking

Step-by-step login process

• Open your browser and go to internetbanking.imb.com.au — the official sign-on page.
• Enter your Member Number and Password. Your password is case-sensitive and must be between 8 and 16 characters (IMB Bank FAQ).
• Optionally, use the Token OTP field if you have a hardware token for an additional security layer.
• Click the login button to access your accounts.

Common login issues and solutions

• Forgot your password? Click the “Forgot your password?” link on the login page (IMB Bank FAQ).
• Lost member number? Contact IMB Bank customer service at 13 15 62 to retrieve it.
• Browser not supported? IMB Internet Banking works with web browsers; if you’re stuck, try clearing your cache or using a different browser.

The implication: your member number is the master key. Keep it safe and you’ll sail through login every time.

How to Sign Up for IMB Internet Banking Australia

Eligibility requirements

• You must already hold an IMB Bank account (savings, transaction, or loan) — sign-up is only for existing customers (IMB Bank official site).
• You’ll need your member number and personal details for verification.

Registration steps

1. Visit the IMB Bank Internet Banking page and click “Register”.
2. Enter your member number, date of birth, and other personal details.
3. Create a password following the 8-16 character rule (letters and numbers, case-sensitive) (IMB Bank FAQ).
4. You’ll receive a one-time security code via SMS to your registered mobile number (IMB Bank official site).
5. Log in to your new Internet Banking account.

The catch: you can’t sign up without being an existing customer. If you’re new to IMB, open an account first.

How to Reset Your IMB Internet Banking Password

Steps to reset password

• Go to the login page at internetbanking.imb.com.au and click “Forgot your password?” (IMB Bank FAQ).
• Enter your member number and date of birth.
• An authentication code will be sent via SMS to your registered mobile number.
• Enter the code and create a new password (8-16 characters, using a mix of upper/lower case, numbers, and special characters) (IMB Bank FAQ).

Password rules and security

• Passwords are case-sensitive (IMB Bank FAQ).
• You can change your password within Internet Banking: go to Other Services > Change Password (IMB Bank FAQ).
• Use a strong password that you don’t reuse elsewhere.

The trade-off: the reset process is quick if your mobile number is up to date, but it’s a roadblock if it isn’t.

What Is the IMB Internet Banking Phone Number?

Customer service contact numbers

• Within Australia: 13 15 62 (IMB Bank Phone Banking page)
• International callers: +61 2 4224 1799
• Phone support is available during business hours.

When to call instead of using online banking

• If you’ve lost your member number and can’t find it.
• If you’re locked out of online banking and the password reset SMS isn’t arriving.
• For urgent account issues like lost cards or fraud alerts.

The pattern: phone support complements online banking, especially when you lose access to your digital keys.

How to Use the IMB Bank Mobile App

Downloading and installing the app

• Download from the Apple App Store or Google Play (search “IMB Bank Mobile Banking”).

• You’ll get a one-time security code via SMS. Enter it, then create and confirm a PIN for the app (IMB Bank official site).

Key features

Why this matters: the mobile app turns your phone into a secure banking hub. Biometric login makes it faster than entering a password every time.
