Information Regarding the iAB Financial Bank Online Banking

Online Banking Login


If you're an active iAB Financial Bank Online Banking customer, your online banking will be automatically migrated the weekend of November 10. Your current iAB Financial Bank Online Banking Username/Login ID will be your 'Login ID' on the First Merchants system unless otherwise communicated to you. Your Login ID is case sensitive, so please be sure to enter it correctly.

Personal Online Banking Login

  • To access First Merchants Online Banking, visit firstmerchants.com beginning Monday, November 13.
  • Follow the login instructions provided in your email using the sign in to online services box in the upper left corner of the page.



  • Once you have entered your Login ID you will see security options displayed. The new system has enhanced security and utilizes a security code through either an automated phone call or a text message to your mobile phone. Click on the 'Continue with Security Code' box and a window will display the phone numbers we have on file for you and prompt you to choose a verification method. Once you have completed your verification, you will enter your temporary password and be prompted to change your password to one that you create.

Phone Call Verification

  • If you would like an automated phone call to one of your phone numbers on record, select the phone number and hit continue.
  • You will receive a phone call that will prompt you to enter the code displayed on your computer screen using your phone. Click 'Phone Call Complete' on your computer when finished.

Text Message Verification

Please note – only phone numbers that we have on file (and that were displayed on the previous screen) are eligible to receive text messages. After hitting “Send Text Message”, follow the prompts and enter the text code on your computer.
