API KEY security for users exporting flows

Recently I've seen a post where a user exposed their API KEY when exporting a flow using one of my nodes. What changes can I make to a node to prevent users from accidentally sharing their API KEY when they export a flow that contains that node?

You can use the credentials feature. It causes the setting to be saved in the credentials file instead of the flows file.

Thank you, I thought I glanced over it awhile back somewhere but now I've found the documentation for it.

Are you developing a node?

(please move this thread to #developing-nodes if yes)
