You do not have to re-register for Online Banking. However there are some steps you will need to follow in order to access your new online banking account:
Step 1: Initial Sign On
If you already have an Online Banking account, you will follow first-time login instructions and then be prompted after your first login to change your password. This is to enhance your security and protect your personal information. The instructions for your first login will be sent to you by mail.
Step 2: Agree to terms and conditions when prompted.
Step 3: Logging on using a new computer or mobile device
The first time you log in on a new computer or mobile device, you will be prompted to enter your phone number or email address to receive a one-time verification code. Once you receive and enter the code, you can either register that computer/device, and never again be asked for a verification code on that device, or save it as a public computer/device and be prompted upon each login to complete the verification process to confirm your identity.
