Oh man, I would love to see passwords become a thing of the past. I'm actually really curious if we can ever manage to really get rid of them, at least I've been able to make my life about easier by using my Google account to log in to many places lately.
I wonder if block chain will provide a solution to this? I know a couple of blockchain based technologies are already aiming to become decentralised identity providers (blockstack for example), maybe that will make the whole authentication problem yet a little easier?
I do believe that with biometrics we could replace passwords in the near future. My thinking is to make use of biometrics and blockchain, which could give us auditing of access management all together. Tying such a solution then to an IAM (Identity and Access Management) solution, we might even be able to provide a single identity over the internet. Where we could then provide access to many things based on your location, skills and even medical history. Having a single identity could even unlock or do away with passports all tegether?
Looking at IAM, we have been doing this for years in the Banking sector. Would be interesting to see this scaled up into social media. But I guess like you said, with Google we are already doing this. They would probably be the at the best position to scale this. But I would like to see more whistles and bells added such as by those provided by e.g. IBM
