1 Passwordless Login through Passkeys

This topic describes the process of passwordless login using passkeys.

A passkey can meet multifactor authentication requirements in a single step. Usernames are often easy to discover; sometimes they're just your email address. Since passwords can be hard to remember. A passkey is an alternative method of user authentication that eliminates the need for usernames and passwords. Passkeys are end-to-end encrypted and stored securely either on your device locally or in a vault, such as your device's keychain or password manager.

Passkeys protect users from phishing attacks. Passkeys work only on their registered websites and apps; a user cannot be tricked into authenticating on a deceptive site because the browser or OS handles verification. Passkey are more secure because every passkey is unique, passkeys tend to be more secure than passwords. That means passwords will no longer be reused across multiple sites and platforms. And because passkeys are generated automatically, users won't need to rely on passwords that are either easy to remember and unfortunately, easy for others to guess or so complicated that they're easily forgotten and also passkey protects from server leaks.

When you attempt to log in to a site that uses passkey technology, the site will send a push notification to the smartphone you used when you registered the account. When you use your face, fingerprint or personal identification number (PIN) to unlock the device, it will create a unique passkey and communicate it to the website you are attempting to access and to give the site or app permission to grant the login request.
