Passwords are often a hassle. Every website wants you to create an account and a password. But it has to be a different password, because if any websites you reuse a password on get compromised, then hackers will have access to all the accounts that have the same password. You could opt for a password manager, but even that can be a hassle for some. Luckily, there’s a new solution that’s been making the rounds on the internet for the past couple of years called passkeys, and it’s already been used many times.
A blog post shared by Google says it has facilitated over a billion passkey-based authentications across over 400 million Google accounts. If you use sites like eBay, PayPal, or WhatsApp, you may already be using passkeys, a password-less authentication system that uses a cryptographic key on your phone to verify your identity when you sign in to a site. And if you use Amazon, Shopify, or Mercari, you might be using them soon. Even password managers like Dashlane and 1Password use them.

Passkeys are the brainchild of the FIDO Alliance, an industry organization working to reduce the internet's reliance on passwords. The first major introduction of passkeys came in 2022, when Apple introduced them at its Worldwide Developers Conference. It didn't take long for them to skyrocket, with major sites like eBay and Uber integrating passkeys early on. And given that Apple and Microsoft are also big players when it comes to passkeys, the real number is likely much higher than a billion.
Additionally, Google says it’s expanding its partnerships for protection . Cross-account protection is a service Google provides to other online services that rely on Google to authenticate logins. If your Google account is compromised, Google will send a notification to participating services, which could prevent automatic logins or account recovery attempts. Google is also expanding the use of passkeys in the Advanced Protection Program for people at high risk of becoming a target of a cyberattack.

What are passkeys anyway?
Passkeys have become a popular method for securing access to personal and confidential information on computers, smartphones, and various Internet devices. By using biometric data such as fingerprints, facial recognition, or iris scans to generate unique passwords for each individual user, passkeys have the potential to replace traditional password-based security. This method not only provides greater security, but also allows for faster and easier access to devices, as you don't have to manually type in passwords.
