You can set up a trusted devices list for the same WeChat ID to help protect your account. You may delete any device from the list, but you'll need to verify your identity when logging in from a deleted device. You can manage your trusted devices by following the instructions below:
1. Add Device to the List
If you've successfully verified your mobile number/email on an infrequently used phone, that phone will be automatically added to your trusted devices list.
2. Change the Name of a Device
Go to「Me」>「Settings」>「Account Security」>「Manage Devices」. Select a device, tap「Name」on the Details page, then edit the new name and「Done」.
3. Delete Devices from the Trusted List
Go to「Me」>「Settings」>「Account Security」>「Manage Devices」>「Edit」. Tap the minus icon next to the device you want to delete.
