Digitally Protected from My Information

As an avid digital citizen, I have way too many logins and passwords.  And because the sites I access have varied security parameters, there is no way that I can use a universal login and password.  How I wish that I could do an iris scan for single sign on for all the sites I want and need to access!  Often I feel like the digital protections provided me reduce (rather than enhance) my access to the personal information I want and need to access.
