BMO Bank Mobile App - Digital Banking: Sign Up for Online Banking - BMO

The BMO Bank mobile app carries most of the functionality from the online banking website into a pocket-sized format. Customers can check balances, pay bills, transfer money, deposit checks by photo, and send money through Zelle, all without visiting a branch. The app is available for iOS and Android and is updated regularly with security patches and feature improvements. For many customers, especially those outside BMO's core Midwest and West Coast markets, the app is the primary way they interact with the bank.

BMO Mobile App

The home screen shows a quick snapshot of all linked accounts, with the option to hide balances for privacy in public spaces. Tapping into an account reveals the full transaction history, searchable by date, amount, or merchant name. The transfer tool handles internal BMO moves instantly and external transfers within one to three business days. Bill pay is fully functional, allowing customers to add new payees, schedule recurring payments, and cancel pending transactions before they process.

Mobile Check Deposit

Mobile check deposit works by snapping photos of the front and back of an endorsed check. The app guides the user to align the check within the frame and automatically rejects blurry or poorly lit images. Most deposits post the same business day if submitted before the evening cutoff, though BMO holds some or all of the funds for new accounts or large checks. A feature called FundsNow can release a portion of the deposit early for eligible customers, which is useful when waiting for a paycheck to clear.

Zelle and External Transfers

Zelle is built directly into the BMO app, allowing customers to send money to friends, family, or service providers using just a phone number or email address. Transfers between enrolled Zelle users typically complete within minutes. For larger or recurring transfers to external bank accounts, the app supports ACH transfers that take one to three business days. There is no fee for standard ACH transfers, though same-day wire transfers still require a phone call or branch visit.

Security Features

The app supports biometric login through Touch ID, Face ID, or fingerprint scanning, depending on the device. Customers can also set up a PIN as a fallback. For added control, the app includes a card lock feature that instantly disables a lost or stolen debit card, plus spending controls that let users set daily transaction limits or restrict card use to certain geographic areas. Real-time push notifications alert customers to purchases, transfers, and login attempts, which helps catch unauthorized activity immediately.

How to Download and Set Up

The BMO Bank mobile app is available on the Apple App Store and Google Play Store. Search for "BMO Digital Banking" and verify that the developer is BMO Harris Bank N.A. After installation, new users log in with the same username and password created during online banking enrollment. Customers who have not yet enrolled in online banking need to do so on the website first; the app does not support standalone account creation.

Troubleshooting Common Issues

App crashes and login failures are usually resolved by updating to the latest version, clearing the app cache, or reinstalling the application. If biometric login stops working, re-enrolling the fingerprint or Face ID in the phone's settings usually fixes it. For persistent issues — like repeated "session expired" errors or missing accounts after the Bank of the West migration — calling customer service at 1-888-340-2265 is the fastest path to resolution. Representatives can verify whether the account is properly linked to the digital profile.
