How to save wifi security code?

I found that after I turned off my M8, I need to re-input the security code when entering a previously accessed wifi AP.

Are there any ways or any softwares to save the security code data so that it does not require to input the security code every time?

Thanks!

Please specify the firmware version when reporting errors! Works fine for me with 0.9.3.1

I'm using firmware 9.2.6.

Thanks!
