This fall, as part of its newest software update, Apple will allow users to make those annoying passwords a thing of the past on apps and online accounts. Microsoft, Google, and about 250 other companies are also seeking to replace passwords with password-less technologies. Passkeys operate as pairs, and each passkey, when generated, is unique. One key sits on the service provider’s server. The other on the user’s device. In the case of Apple, the two keys are connected by Apple on the backend, and the user authenticates this with FaceID or TouchID.
