Protecting yourself

Ne mordez pas à l'hameçon video


When you connect to the Internet, the Internet also connects back to you. Even before you connect to the Bank's web site, someone out there could potentially get access to your computer. Also, as you surf the Internet, there is a trail of information left behind.


Decrease your chances of being hacked by following the tips in our ‘Don’t Take the Risk!’ video.

Verify Web Addresses

For all BMO websites

When you're banking online, be sure to verify BMO's website address in the address bar of your web browser. Valid BMO website addresses include:

If you are using a current browser, you will see our web address is green, another sign that you have reached our legitimate web site.

Protect passwords and PINs

Your password is your best protection

Here are a few simple ways you can protect your passwords.

  • Memorize your debit and/or credit card passwords and/or PINs.
  • Never write down a password or PIN.
  • Change your passwords and PINs on a regular basis (every 4-6 months). Always choose a strong password.
  • Don't let web sites store your passwords. While this can seem convenient, storing passwords grants anyone with access to your computer, access to your accounts and information.

Clearing your cache

These instructions will remove the information stored on your computer that lists where you have surfed on the Internet and the passwords you have provided to websites:

If you're using any version of Microsoft Internet Explorer :

  • From your browser menu select: Tools.
  • From the View drop-down menu select: Internet Options.
  • On the "General" tab (the first one at the top) look for the "Temporary Internet Files" section near the middle of the window.
  • Click on the "Delete Files" button.
  • A new window appears. Check the box that says: "Delete all offline content". Click the "OK" button. An hourglass tells you that files are being deleted.

If you're are using Firefox:

  • Click "Tools" and select "Options" on the Firefox menu bar.
  • Click the "Privacy Icon" on the Option menu bar to open the Privacy Properties.
  • Click "Clear" across from the Cache/Private Data option.
  • Click "Ok" to return to the browser main page.
  • Exit and re-launch the browser.

For other browsers, please refer to your browser's documentation on memory/disk caching.

Additional Security measures

Keep your computer secure when you're not around.

  • Do not step away from your computer when you're logged in to a secure session.
  • Always log off when you have finished banking online.
  • If your session is idle for more than 10 minutes, you will automatically be logged off.
  • Once you've logged off, delete all traces of your session from your computer's memory by clearing your cache.
  • If you can avoid it, never use a public computer for your online financial transactions.

Protect your Pin

Millions of Canadians use debit cards and credit cards for multiple transactions every day. BMO payment systems are more secure than ever thanks to chip technology, the latest innovation in payment systems.

Do your part to keep your account safe from intrusions by safeguarding your BMO Debit Card and PIN. Here are some smart ways you can counteract fraud.

  1. Change your PIN often. You can change the PIN on your BMO Debit Card and BMO MasterCard at any BMO ATM.
  2. Shield your PIN when conducting transactions at an ATM or at a point-of-sale terminal.
  3. Never let your banking card out of your sight when conducting a transaction at a point-of-sale terminal. Always remember to take your banking card and transaction record with you once your transaction is complete.
  4. Check your statements and balances regularly to verify all transactions have been properly documented. If entries do not accurately reflect transaction activities, for example, if there are missing or additional transactions, you should contact your BMO Bank of Montreal branch immediately.
  5. If your banking card is lost, stolen or retained by an ATM, notify your BMO Bank of Montreal branch immediately.
  6. Your banking card and PIN are the keys to your account(s). Never disclose your PIN to anyone—not even BMO. You are the only person who should know it.
  7. Your PIN is your electronic signature—memorize it. If you suspect that someone knows your PIN, change it immediately or contact your BMO Bank of Montreal branch to cancel the card.
  8. When selecting your PIN, use obscure information rather than your telephone number, date of birth, address or social insurance or social security number.
