How do I sign in to Online Banking for Business for the first time? 

Finding your Customer ID and User ID  

Online Banking for Business is designed for multiple users. That's why you have:  

• a Customer ID, which represents your company  
• a User ID, which represents you  
• your password 

You can find your Customer ID and User ID in our “Welcome to Online Banking for Business” email in your inbox. 

Can’t find our welcome email? Ask your Primary Customer Administrator (PCA) or BMO representative to generate one for you. 

Important: For your protection, please record your Customer ID and User ID in a safe place, delete the welcome email from your inbox and then empty your deleted items folder. 

Signing in for the first time 

Once you’ve found your Customer ID and User ID, it’s time to create your new password and sign in for the first time: 

1. On the Sign-in page, at www21.bmo.com, next to the “Password” field, select Reset Password. 
2. Enter the Customer ID and User ID you received in the welcome email and your email address we have on file. Then select Continue.  
3. If the information matches our records, we'll email you a temporary password.  
4. Back on the Sign-in page, enter your Customer ID, User ID and temporary password. Then select Sign In.  
5. Once you’ve signed in with the temporary password, you’ll need to verify your identity with a 6-digit code we send to your mobile phone. Don't have a Canadian or U.S. mobile number? 
6. Enter the 6-digit code into the “Verification Code” field.  
7. When prompted, create and verify your new permanent password. Then select Confirm.  

You’ve successfully created your permanent password. You can use it to access Online Banking for Business on your desktop or our mobile app.
