How Can I change default pin code?

Hi Guys,

Anyone know how can I change default pin code from 1234 to Anything else? I arm camera by Alexa and I don’t like this funny pin code

I had to set a PIN when I added the skill. I didn’t even know there was a default one. There wasn’t when I did it. See what the others say.

if you try 1234 will work easy but problem is that pass not safe anymore and need to change to own one
