Explainer - what are passkeys, and why they may replace passwords

Passkeys are a significantly safer replacement for passwords and other phishable authentication factors' ', Says Sarraf (Google Chrome product manager). Passwords have been the first line of defence in users' digital lives, and they are also risky. Hackers can access passwords, phishers can try to steal them, and people may create passwords that are easy to guess. Here google wants users to create passkeys. “They cannot be reused, don't leak in server breaches, and protect users from phishing attacks,” says the google chrome manager. There is also good about passkeys that they can be used in various browser ecosystems and operating systems,  and can be used in apps and websites also.

How to use passkeys on Google Chrome 

Passkeys are now available for Windows 11, macOS, and Android with the latest Chrome update. Users can use passkeys to sign in to apps and sites which support them. 

Passkeys will be securely synced on android through a google password manager. Moreover, other password managers that support passkeys will also sync them. Users will be prompted to use passkeys on sites and apps instead of passwords.” Once you have a passkey saved on your device it can show up in autofill when you're signing in to help you be more secure” explains google manager.
Desktop users can also use passkeys from nearby mobile devices and since “Since passkeys are built on industry standards, you can use either an Android or iOS device” says google manager Sarraf in a blog post. 

“When you sign in this way, your passkey does not leave your mobile device. Only security-generated code is exchanged with the site so, unlike a password, there is nothing that could be leaked” he further added.
