As of March 2015, M&T Bank account holders can access their accounts online. Visit the official bank website, locate the Log In to Online Banking for Business and Personal section on the right of the page, enter the user ID and passcode, and then click the Log In button.
Those who have an M&T Bank account without current online access can sign up for this service online.

This service allows users to access checking and savings account information, including account balances, and users can also transfer money to other accounts and pay bills online.
