Over the years, some companies have tried to create a single password that works across all services. It has never caught on, most likely due to a lack of trust. To me, having a single password is the perfect solution. One place to sign up, one username and password (or a biometric combination), and it works everywhere. All web sites and computer hardware would connect and authenticate to it. I'm guessing, however, that's not going to happen very soon since it would require the cooperation of most companies who aren't motivated to work together on this.
I'd love to see all of these technologies combined together: I sit down at a PC and it auto detects the smartphone in my pocket. The smartphone prompts me to scan my finger with the built-in scanner, and after I do, I am securely logged into the PC. Sounds like a dream.
I'll continue to wait patiently. How about you?
