Need help to enable Apple Watch passcode which is grayed out

Hi Markrt_09,

Thanks for posting in Apple Support Communities! Do you use profile configurations on your Apple Watch? Is it managed by work or school? You may not be able to set a passcode for your Apple Watch if you have passcode restrictions set up on your iPhone. This article goes over this: Set passcode restrictions for an Apple Watch.

You can check for restrictions on your iPhone by following the guidance here: Use parental controls on your child's iPhone, iPad, and iPod touch

Cheers!
