# Error in Binding Mobile Token?

<!-- image-todo -->

**The prerequisite for binding and using mobile tokens is: the mobile phone time is synchronized with the bastion host time**

Check the configuration in case of binding errors:

1. In the Bastion System - System Maintenance module, choose cn.ntp.org.cn and synchronize the bastion host time

<!-- image-todo -->

2. Check and synchronize mobile short time

3. Open the mobile applet and delete the currently bound data in the applet
