Hello, if it is the first time for you to use ukey of Postal Savings Bank, you need to change your password first. Please plug the uk into the usb interface of the computer, and the system will automatically install the uk management tool. After successful installation, the icon of the British management tool will be displayed in the lower right corner of the computer screen. If the icon of the British management tool does not appear, please open my computer and double-click the British drive disk to complete the software installation. After the installation is completed, a prompt window for changing the UK password will pop up. The initial password of uk is "88888888", and the new password can be set to any character of 6- 12, such as c 1b2c3, which is case-sensitive. After modification, ukey needs to be inserted when making payment. You can insert the UKEY, click OK, and enter the ukey password. I hope my answer is helpful to you.
