The password has significant problems, including users choosing weak passwords that are easy to guess, and password databases being breached frequently. To address these issues, researchers have been seeking a replacement for the standard password, with various approaches trying to make passwords more secure over the years. One such approach is two-factor authentication (2FA), which adds an extra layer of security by requiring users to have another device, commonly a smartphone. The leading emerging solution for replacing the password is FIDO2, a protocol that aims to remove passwords entirely from the authentication process. FIDO2 uses hardware-based tokens to prove user identity and is more secure than traditional password systems. However, there are also disadvantages to FIDO2, such as its compatibility with commonly used web browsers and public key cryptography requirements. Ultimately, whether FIDO2 or another technology like biometrics will replace the password remains to be seen, but it's clear that the password's time is running out.
