# Security Policy

#### Troubleshooting help for Security policies  
  


##### **"Security policy with this name already exists in this enterprise"**

Choose a different **Description Name**.

##### **"Cannot delete security policy because it is used in configuration"**

Remove the policy from every device group that uses it, then delete it again.

##### **Devices have no lock screen**

**Lockscreen disabled** is **Yes** by default in a new policy. Open the policy and switch it to **No**.

##### **The minimum character fields have no effect**

**Minimum letters**, **Minimum lower case**, **Minimum non letter**, **Minimum numeric**, **Minimum symbol** and **Minimum upper case** only apply when **Quality** is **Complex**. **Minimum length** also applies to the other password-based qualities.

##### **Devices lost their Wi-Fi networks**

Turning **Common criteria mode** off after it was enabled can remove the user-configured Wi-Fi networks on the device. Push the needed networks through a Network and Connectivity policy.
