The sun is setting on the era of password security. Passwords are too weak and too big a target to keep using them. In their place, companies are adopting passwordless authentication systems that use more secure forms of identity verification. Passwordless authentication gives you a more reliable, affordable, and secure way to prove that the person trying to access your company’s resources is actually who they claim to be. Rather than relying on something the person knows, passwordless authentication relies on more secure factors such as security keys or biometric identification. The problem with passwords goes even farther, with over 84% of breaches being due to vulnerable credentials. Passwordless authentication offers many benefits beyond security by making networks easier to manage and by improving the user experience. It streamlines network management, improves user experiences, and makes compliance easier. There are several types of passwordless authentication, including biometric identification, authentication apps, security keys, and messages. Behind the scenes, passwordless authentication is based on a system of cryptographic key pairs. Modern companies are using passwordless authentication to improve security, simplify user experience, and improve efficiency. The risks passwords create are well-known, and the promises of passwordless authentication are enticing. Companies usually take a phased approach with their passwordless migrations. Passwordless zero trust security replaces outmoded identification factors with more secure approaches that make companies more secure, simplify the user experience, and improve efficiency.
