Creator of the device here. I'll address the few points that were raised in the comments section: - Our device is used by thousands of users from all ages... even by elderly people - We're about to launch a smaller and simpler version (no tactile interface, just a clickable scroll wheel), which will be sold at less than $50. Mooltipass Mini Prototypes have already been used for 2 months, with a better acceptance factor than the standard version - We made a password keeping solution seeing that still very few services implement the different mechanisms created by the FIDO alliance (U2F & others). Unfortunately passwords are here to say for several years at least.
