2FA. As much as I like password managers, I feel like they're solving a problem that has come about because our method of authenticating users hasn't kept up with developments in tech. some kind of 2FA variation (probably not what we currently have) that uses trust chains anchored at individuals will hopefully revolutionize authC. Duo, Yubikey, etc are all really effective steps in the right direction if not already great products that are actually effective and do what they say they will. mass market is the next hurdle.
