The end of passwords

Companies are finally shifting away from notoriously insecure alphanumerics to other methods of authentication.

In the early 1960s, MIT professor Fernando Corbató was developing a new kind
of shared computer system and wanted a way for people to be able to protect their private files. His solution was a password. Over the years, Corbató’s fix won out over other means of authentication and became the standard way we log on to pretty much everything, everywhere.

The catch? Passwords are inherently insecure. They can be stolen, guessed, or brute-forced. But mostly, people just use bad ones. (And, worse, reuse them.)

Password managers like Dashlane and 1Password can track all those various alphanumerics for you and even replace the weak ones. But password management is a half measure when it comes to security. The real action is in eliminating passwords altogether.

The process is already underway. Enterprise-oriented companies like Okta and Duo, as well as personal identity providers like Google, offer ways for people to log in to apps and services without having to enter a password. Apple’s facial recognition system has taken biometric login mainstream. Most notably, Microsoft announced in March 2021 that some of its customers could go completely passwordless, and it followed up in September by telling people to delete their passwords altogether. Those other methods of authentication? They’re finally winning.

You’ve probably experienced this for yourself. You go to log in to a site or fire up an app, and instead of being asked to enter a password you get a prompt to enter a six-digit code from your authenticator app, tap a notification on your phone, or click a link sent to your email. Or maybe you just need to raise your phone to your face. Easy peasy.

As for typing in a bunch of characters and symbols you have to recall, write down, or store in a database? Good riddance to all that.
