Plugin update wipes security.store file

Software Versions

All existing versions.

Recommended solution

Hey @fow5040, thoughts on saving the security store file to plugin settings folder? There is already a Flow API method for that.

Yeah I'd be down to do this! Honestly I'd also like to put a proper settings UI in as well so we can update these settings. I'll look around and try to copy something from similar plugins
