Github Authentication with Passkeys

The GitHub Passkeys feature enhances security by replacing passwords and two-factor authentication with cryptographic keys, simplifying the login process while making it more secure. Passkeys are stored in a user-controlled authenticator and are utilized for signing in, sudo mode, and password resetting. They offer a higher level of phishing resistance compared to traditional methods. Moreover, cloud-backed passkey services facilitate synchronization across multiple devices, ensuring convenience and security in accessing GitHub accounts across various platforms.

For a detailed explanation, check GitHub's official documentation.

Syncing passkeys via providers like iCloud or Google accounts indeed facilitates recovery in case of device loss. However, it also poses risks:

1. Unauthorized Access: If someone gains access to your provider account, they could access your passkeys.

2. Provider Security Breach: If the provider experiences a security breach, your passkeys could be compromised.

3. Sync Errors: Syncing errors could result in outdated or incorrect passkeys.

4. Privacy Concerns: Your passkey provider will have access to your authentication data, which could raise privacy concerns.

Always ensure strong security measures on your provider accounts to mitigate these risks.

Here are some suggested best practices:

1. Use Secure Vaults: Choose secure vaults like 1Password or Keeper Security that support Single Sign-On (SSO) and have features for exporting logs to a SIEM or security data lake, catering to business security needs.

2. Disable iCloud Keychain Syncing: If using Apple devices in a corporate environment, utilize Mobile Device Management (MDM) to disable iCloud keychain syncing.

3. Multi-Factor Authentication (MFA): Employ MFA on your vault accounts for additional security.

4. Regular Audits, Educate Team Members, and Avoid Public Cloud Sync: Maintain these practices to ensure ongoing security and awareness among team members.
