@kestutis-mockus I still think it is too complicated for what the basic feature actually provide (which is weak security) and it relies on a atsha which on its own implement stronger security based on personalization, something the entire password feature was designed to circumvent. But if you feel the feature is strongly desired, feel free to file a pr (and maintain) the feature and if it is well designed it can be incorporated in the core. But personally I don't feel it gives enough benefit for being worth the effort of implementation and maintenance. I'd rather focus on development of the next generation security which is designed to replace the current encryption/signing solution in its entirety (the current solution will remain an option for those who prefer it though). But this will be first in mysensors v3.
