Web Authentication (WebAuthn) is a web standard that defines an API for authenticating users to websites and web applications using public-key cryptography. WebAuthn is a more secure alternative to traditional password-based authentication, as it eliminates the risk of phishing and password theft. WebAuthn requires the user to have a registered authenticator, such as a security key or a mobile phone with a built-in fingerprint sensor.

Microsoft WebAuthn API Developer Guide

WebAuthn is a W3C standard that allows web applications to use USB security keys, as well as built-in fingerprint readers and mobile device biometrics, for strong two-factor authentication. This guide provides developers with the information they need to implement WebAuthn in their Microsoft applications.

Key Concepts

Credential: An object that represents a user’s authentication credentials.
PublicKeyCredential: A credential that contains a public key and a set of parameters.
Attestation: A statement that proves that a credential was created on a specific device.
Authenticator: A device that generates and stores credentials.

Implementation

The WebAuthn API can be used to perform the following tasks:

Register a new credential.
Sign in with an existing credential.
Get a list of all registered credentials.
Remove a registered credential.

Security Considerations

When implementing WebAuthn, it is important to consider the following security considerations:

Use strong attestation mechanisms to ensure that credentials are only created on trusted devices.
Store credentials securely to prevent unauthorized access.
Implement rate limiting to prevent brute-force attacks.

WebAuthn API for Microsoft Applications

The WebAuthn API provides a standardized method for websites and web applications to securely authenticate users using a range of factors, including hardware-based security keys, biometrics, and platform-specific authentication mechanisms. This API has been implemented in Microsoft applications such as Azure Active Directory (AAD) and Microsoft Edge.

By integrating WebAuthn, Microsoft applications can enhance user security by offering strong two-factor or multi-factor authentication options. Users can choose from various authentication methods, such as fingerprint scanners, USB security keys, or facial recognition. This reduces the risk of unauthorized access to user accounts and data.

The WebAuthn API also simplifies the authentication process for users, as they can use the same authentication methods across different Microsoft applications and devices. This eliminates the need to remember multiple passwords and reduces the likelihood of phishing attacks.

1Password Integration with Microsoft WebAuthn API

1Password integrates with Microsoft’s WebAuthn API, providing enhanced security for Microsoft accounts. This integration:

Eliminates the need for SMS-based two-factor authentication: Users can securely authenticate using their 1Password account without relying on unpredictable SMS codes.
Protects against phishing attacks: 1Password verifies the authenticity of the Microsoft login page, reducing the risk of being tricked into entering credentials on a malicious website.
Simplifies the login process: Users can easily sign in to Microsoft accounts with their 1Password account, eliminating the need to remember and enter multiple passwords.
Supports multiple devices: Users can authenticate from any device with the 1Password app installed, providing flexibility and convenience.

1Password Implementation of Microsoft WebAuthn API

1Password, a popular password manager, has implemented support for the Microsoft WebAuthn API, allowing users to securely authenticate to websites without the need for passwords. WebAuthn is a browser-based protocol that uses public-key cryptography to verify user identity.

By integrating WebAuthn, 1Password provides users with a more convenient and secure authentication experience. Users can use their existing 1Password credentials to authenticate, eliminating the need to remember and manage multiple passwords. Additionally, the WebAuthn protocol uses strong cryptographic mechanisms to protect user data, making it less vulnerable to phishing attacks or password breaches.

Microsoft WebAuthn API with 1Password Integration

The Microsoft WebAuthn API enables passwordless sign-ins that are more secure than traditional methods. With 1Password integration, users can easily use their 1Password account to create and manage WebAuthn security keys. This integration provides a seamless and secure passwordless experience for users of Microsoft Edge and other browsers that support WebAuthn.

Microsoft WebAuthn API for 1Password Users

The Microsoft WebAuthn API and 1Password provide a secure and convenient way for users to sign into their Microsoft accounts using a FIDO2 security key stored in 1Password. This integration enhances account security by replacing traditional passwords with stronger, hardware-based authentication.

With 1Password’s WebAuthn support, users can easily register their security key with Microsoft and use it to sign in to their accounts without the need for a password. The key is stored securely within 1Password’s encrypted vault, ensuring its protection from phishing and other attacks.

The integration is simple to set up and offers a seamless user experience. By leveraging the Microsoft WebAuthn API and 1Password, users gain robust account protection and a more convenient sign-in process.

Using 1Password with Microsoft WebAuthn API

1Password is a popular password manager that offers a variety of security features, including WebAuthn support. WebAuthn is a newer authentication standard that relies on hardware-based security keys to provide strong authentication.

To use 1Password with WebAuthn, follow these steps:

Sign up for a 1Password account and install the 1Password browser extension.
Enable WebAuthn support in 1Password by navigating to Settings > Security > WebAuthn and clicking the "Enable WebAuthn" button.
Register a security key with your 1Password account by following the instructions on the 1Password website.
You can now use your security key to sign in to websites and apps that support WebAuthn.

When prompted to authenticate, simply insert your security key into your computer’s USB port and touch the sensor. 1Password will automatically fill in your credentials and sign you in.

Best Practices for Using Microsoft WebAuthn API with 1Password

Use the latest version of Microsoft Edge or Google Chrome: These browsers provide the best support for WebAuthn.
Enable WebAuthn in 1Password: Go to 1Password’s settings and enable the "Use WebAuthn for sign-in" option.
Use a strong master password: Your master password is the key to your 1Password account. Make sure it is strong and unique.
Enable two-factor authentication (2FA): 2FA adds an extra layer of security by requiring you to enter a code from your phone or email when you sign in.
Register multiple authenticators: Register more than one authenticator, such as a hardware key, biometrics, or a mobile app, to provide backups in case one is lost or stolen.
Use a hardware security key: Hardware security keys provide the highest level of security for WebAuthn authentication.
Store your recovery codes: If you lose your authenticator or master password, you’ll need recovery codes to access your account. Store them securely.

Troubleshooting with 1Password

Common Issues and Solutions:

WebAuthn API not supported by browser: Ensure that the browser used supports the WebAuthn API.
Missing or incorrect Manifest JSON file: Verify that the Manifest JSON file is present in the root directory of the web application and that it contains the correct settings.
Invalid or outdated 1Password extension: Ensure that the 1Password extension is installed and up-to-date in the browser.
WebAuthn credentials not saved in 1Password: Check if the user has saved their WebAuthn credentials in 1Password.
Incorrect sign-in URL: Ensure that the sign-in URL specified in the Manifest JSON file matches the URL where the user is attempting to sign in.
Mixed content issue: Verify that the web application is served over HTTPS (not HTTP).
Debugging mode enabled in 1Password: Disable debugging mode in 1Password to prevent potential interference.
Inconsistent browser state: Clear the browser’s cache and cookies, and restart the browser.
