Maintaining a strong and unique password is the first line of defense for your digital identity at the Bank of Montreal (BMO). Whether you are updating your credentials as a proactive security measure or need to regain access after being locked out, BMO provides two distinct paths for password management. If you still remember your current details, you can quickly update them through your profile settings; if you have forgotten them, a secure reset process is available using your banking card.
Security experts in Canada recommend rotating your banking passwords every three to six months to mitigate the risk of unauthorized access. BMO’s digital platforms—both the desktop Online Banking portal and the BMO Mobile app—are designed to facilitate these changes securely, utilizing Multi-Factor Authentication (MFA) to ensure that only the verified account holder can modify sensitive login credentials.
BMO Password Management Options
| Category | Details |
|---|---|
| Update Existing Password | Completed while signed in under "My Profile & eDocuments." |
| Reset Forgotten Password | Completed from the login screen using the "Forgot your password?" link. |
| Security Requirement | Requires a case-sensitive alphanumeric string (8-16 characters). |
Algorithm: How to Change Your Password While Logged In
- Step 1: Sign in to BMO Online Banking on your desktop or open the BMO Mobile app.
- Step 2: Navigate to the My Profile & eDocuments tab (on desktop) or the More menu (on mobile).
- Step 3: Select the Change My Password option from the list of security settings.
- Step 4: Enter your Current Password first to verify your identity, followed by your New Password.
- Step 5: Confirm the new entry and click Submit. You will receive an immediate confirmation that your credentials have been updated.
Pro-Tip: After changing your password, the ultimate efficiency hack is to enable Biometric Sign-In (Face ID or Fingerprint) on your BMO Mobile app. This securely links your new password to your unique biometrics, allowing you to bypass manual typing and SMS verification codes for future daily logins while maintaining peak security.
Troubleshooting Password Change Issues
- MFA Code Delays: If you are resetting a forgotten password and the 2-Step Verification code is delayed, check your mobile signal. If the SMS fails, select the option to receive an automated voice call to verify your identity.
- Browser Sync & Cache Errors: If the password change page freezes or loops, your browser's saved passwords or cache may be conflicting with the update. Clear your cookies and cache, or complete the change using a secure Incognito/Private window.
- Locked Account (Suspended Access): If you enter your current password incorrectly three times while trying to change it, your access will be suspended. You must use the Forgot your password? workflow on the sign-in screen to reset your access using your Client ID and security questions.
Frequently Asked Questions
Can I use a password I have used previously at BMO?
No. BMO's security system maintains a history of your previous passwords. You must create a new, unique password that you have not used recently to ensure the highest level of account protection.
Does changing my password on the app also change it for desktop banking?
Yes. Your BMO Digital Banking credentials are universal. Changing your password on the BMO Mobile app will automatically update the login requirement for the desktop Online Banking portal as well.
