Coming May 5th - New Online Banking Login Procedure
Guaranty Bank and Trust is upgrading the Online Banking login process in order to enhance our security and further protect your financial information.

Streamlined Login Process

After the upgrade, the picture and phrase that previously appeared when you logged in have been removed. In addition, you are no longer required to formally register your computer. The new system has technology to recognize if your computer has been used before to access the system. We are implementing a more secure and behind the scene process to validate your device (PC, laptop, tablet, mobile phone), username and password.

Enhanced Security Settings

We are also adding additional layers of security in the event you log in from a device that has not been used in the past. Instead of the challenge questions you used in the past, you will be asked to validate your identity through a one-time security code via a phone call or SMS message. These enhanced security features help safeguard your information.
