Algorithm: How to Report Fraud via BMO Digital Banking
- Step 1: Sign in to BMO Online Banking or the BMO Mobile app using your Client ID and secure password.
- Step 2: Enter the 6-digit Multi-Factor Authentication (MFA) code sent to your registered mobile device to authenticate your session.
- Step 3: Select the impacted account or credit card from your dashboard.
- Step 4: Click on Manage Card (for credit cards) or navigate to the Security Centre tab.
- Step 5: Select Report Lost or Stolen or Report Fraud to begin the automated replacement process and flag suspicious transactions.
Pro-Tip: The most effective efficiency hack for urgent fraud prevention is the Lock My Card feature. If you suspect your card is compromised but haven't spoken to an agent yet, log into the BMO app, go to Manage Card, and toggle Lock your card. This instantly prevents any new purchases or withdrawals while keeping your online banking access active, giving you time to contact the fraud department without further risk.
Troubleshooting Fraud Reporting Hurdles
- Delayed MFA Codes: If you are trying to log in to report fraud and the security code is delayed, check your cellular signal. If the SMS fails, choose the Voice Call option to receive the code via an automated call. This is often faster during network congestion.
- Unfamiliar Merchant Descriptions: Before calling the fraud line for a suspicious charge, Google the merchant name or location shown on your statement. Many companies use a "Doing Business As" (DBA) name that differs from their brand name; identifying a legitimate charge yourself can save hours on the phone.
- Locked Digital ID: If you suspect your online banking password was compromised, attempt to log in. If BMO has proactively locked your ID for your protection, do not attempt to reset it online. Instead, call 1-877-225-5266 immediately to verify your identity and have a representative manually restore your access.
Frequently Asked Questions
How do I report a suspicious text message (Smishing)?
Take a screenshot of the message on your phone and email it as an attachment to [email protected]. Do not click any links or reply to the sender, as this confirms your number is active to the fraudster.
Am I liable for fraudulent charges on my BMO account?
Under BMO's Zero Liability and Electronic Banking Guarantee, you are typically protected from unauthorized transactions as long as you have kept your PIN and password confidential and reported the loss or fraud as soon as you became aware of it.
What should I do if my physical chequebook is stolen?
Visit your local BMO branch or call the personal banking line immediately to place a Stop Payment on the specific cheque numbers and, if necessary, close the account and transfer your balance to a new account number to prevent further unauthorized withdrawals.
