I have an apple touch need to unlock Activation Lock.

Activation Lock is intended as a theft-deterrent mechanism. A theft deterrent that is easy to bypass would not be much of a deterrent.

Nobody here in the Apple Discussion Forums can help you clear Activation Lock.

To clear an Activation Lock, you will need the password of the associated Apple ID, or the original purchase receipt and a discussion with Apple Support, or similar proof of ownership.

A remote unlock using iCloud is available if your daughter is still available and is inclined to unlock this device.

Again, only the person with the credentials to the Apple ID holding the lock, or Apple, can clear this lock. For Apple to clear the lock, you will have to provide a receipt with proof of original purchase and with matching serial number or IMEI, legal paperwork from an inheritance, or other similar proof of ownership materials.

For recovering access to your daughter’s Apple ID, if they are the holder of the Apple ID associated with the Activation Lock:
