According to a blog post published Thursday by Google, a passwordless login method will allow users to use their phones as the primary authentication device for apps, websites, and other digital services. Unlocking the phone with whatever action is set as the default — entering a PIN, drawing a pattern, or using fingerprint unlock — will then be sufficient to sign in to web services without the need to ever enter a password, made possible by the use of a unique cryptographic token called a passkey that is shared between the phone and the website.
