Great idea, I can see that this would be awesome on services I use seldom and often forget my password anyway. But do the average user really care enough to bot

Great idea, I can see that this would be awesome on services I use seldom and often forget my password anyway. But do the average user really care enough to bother with email? or for SMS, will they give away their phone number? Remembering users for a long time also opens up for other breaches. Anyway it is awesome that people are working alternatives!
