Solving Problems with Authentication discusses common authentication attacks and issues with passwords. It notes that passwords are inherently insecure due to susceptibility to brute force attacks and human error. While services have implemented measures like multifactor authentication and minimum password requirements, these solutions can be complex, costly, and disruptive. The document recommends removing passwords and using alternative authentication methods like biometric authentication and physical security keys. It also suggests decentralizing authentication and allowing multiple login options to improve security without reducing usability.
