Is it safe to pass data via watchConnectivity

Hi,

I am developing a dependant watch app and need to pass some data from the phone to watch and vice versa to sync up(Imagine login credentials). So is it secure to pass data as plain text from the mobile to watch app and vice versa? Can hackers or middleman can listen and gain the data within the communication process? Or is the data encrypted by any means default by apple?

Is it safe to pass data via watchConnectivity

I do think so:

 all communications between iPhone and Apple Watch are encrypted

Read in this Apple's doc:
