Since the 1960s, passwords have undergone quite an evolution. Despite the changes, strong passwords are still an essential first line of defense in cybersecurity regardless of whether you’re working on military computers or social media.
But a single password for a laptop or account is not enough to stop hackers and other malicious figures from accessing vital information anymore. Fortunately the advent of multifactor authentication (MFA) has introduced a method that allows both individuals and corporations to strengthen their accounts and keep their sensitive information protected.
What is a passwordless future?
The idea of a passwordless future is not new. In fact, many tech giants and some new players are already building the infrastructure to make it a reality. In a passwordless future, instead of relying on passwords, we can use biometric authentication, physical security tokens, one-time passwords (OTP), or authentication apps to securely access accounts.
The idea here is to avoid transmitting secrets across the network, by validating the user’s identity remotely instead. The most secure way to do that is via the FIDO standard, using public-key cryptography (PKI). With FIDO, the end user has a private cryptographic key and the system has a corresponding public key. When the end user solves a local challenge, such as providing a valid fingerprint, the login request is signed with the private key and can be validated with the public key to grant access.
