Some websites and services allow you to log in without a password, but this still requires a username/password pair, and leverages an additional device to log in. Nevertheless, even imperfect 2FA is better than not using 2FA at all.Īn improved form of two-factor authentication is the use of a physical security key you can even use a security key to protect your iCloud account.

Even some forms of 2FA are imperfect at protecting accounts, especially in scenarios where a phishing site acts as a man-in-the-middle relay between the victim and the real site (as discussed on episode 283 of the Intego Mac Podcast).

This involves entering something you know (your user name and password) along with something you have (a code received by SMS or generated by an app) and/or something you are (biometrics, like Face ID or Touch ID). Over time, multifactor authentication or MFA - more commonly known as two-factor authentication or 2FA - was developed to thwart hackers. The majority of computer users today still create passwords that are insecure and reuse them across multiple sites, and rarely use multifactor authentication.

While many people use password managers that generate long pseudorandom passwords-which is often the best option available, along with multifactor authentication-this can still be an onerous process. It’s important to create unique, strong passwords to prevent hackers from accessing accounts, either via credential stuffing, or via brute force or dictionary attacks-automated methods to try millions of words, common passwords, and likely variations.Īs the stakes have risen, and as hackers have developed more techniques for breaching accounts, the need has come for more secure authentication methods. Not only because passwords protect sensitive data, such as military secrets and bank accounts, but because there are more threats to computer security as hackers attempt to get access to accounts.įor many years, it was normal for people to use the same combination of username and password on multiple websites and services, but continuous data breaches of major companies had led to leaks of these username/password pairs, allowing hackers to try to use them on different services, in a technique called credential stuffing. Over time, the need for more secure passwords has become essential. Passwords were, in some cases, encrypted to ensure that nobody other than the intended user could access them-though that wasn’t universally true in some early systems. With the advent of the Internet, authentication to online services via a username and password became essential, because of the need to log into computers remotely.

However, it wasn’t until the release of Mac OS X in 2001 that separate user accounts became more mainstream. On the Mac in particular, basic functionality for creating separate local user accounts was added in 1999, to Mac OS 9. While you needed passwords to identify yourself on computers at universities and in some businesses, individual users rarely used them. The importance of password securityīefore the Internet, password security was somewhat less important, because anyone wanting to access a computer generally needed physical access. The combination of a username and password is supposed to ensure that someone logging into a computer, website, or service is uniquely identified, authorized, and has access only to their own data. With computers, passwords became the only way to identify who should have access to various computer systems. Simple spoken passwords were also used to gain entry to speakeasies in the United States during prohibition this clip from the Marx Brothers’ film Horse Feathers shows some lax security in that context. They have been used in military contexts to separate friends from foes.
Passwords have been used for thousands of years as a means of authenticating people.
Advantages and disadvantages of passkeys.How passkeys work on Macs, iPhones, and iPads.In this article, I will explain what passkeys are, how they work, and why they may be the future of secure authentication on websites and in apps. There are many advantages to using passkeys instead of passwords. Passkeys are an authentication technology designed to replace passwords. When Apple released iOS 16 and macOS Ventura in late 2022, they introduced support for passkeys.
