Im sorry that my English is not good.
I trying to connect PS Move with usual Windows wizard for adding a new BT，and need a password
。But I don't know the PS3's password，I don't know what to do。

Yes, the third option is right (without a code). But it's a bit tricky to get PS Move connected using standard Windows wizard. That's why iPi Recorder has its own pairing procedure.

I use the ipi recorder pairing, but it is always to stay here. I changed a lot of BT Dog also can't solve, what should I do.

During pairing, do you press the PS button each time the LED stops blinking and goes off?

When the led lights stop, I press the PS button, again and again, still not work after half an hour,what should I do!!!!!

I use the Motioninjoy gamepad tool, ipi recorder can't find the bluetooth driver，I'm very tired!!!!!

When you use Motion in Joy drivers, you should not use pairing procedure in iPi Recorder. After PS Move is paired with BT adapter in DS3 tool, and is on (LED constantly on) - it is visible in iPi Recorder without need to press the ADD NEW button.

According to you said method also tried many times, but still not working，Update all the drivers,Bought a lot of BT DOG.........I'm so lost!!!!!Brother, is there any way
