Step by step

  1. 1 min

    Require Touch ID for Safari AutoFill

    Open Safari and select Settings from the menu bar. Navigate to the AutoFill tab and ensure that 'Usernames and passwords' is checked. Verify that 'Require Touch ID or password to fill passwords' is enabled in the Safari Settings security preferences.

    Note: This prevents Safari from autofilling credentials unless you authorize the action via Touch ID or your Mac login password.

    Enable Biometric Unlock in Google Chrome

    Launch Google Chrome and click the three-dot menu icon in the top right corner. Select Settings, then navigate to 'Autofill and passwords' and select 'Google Password Manager'. Click Settings in the sidebar and toggle on 'Use Windows Hello' (labeled 'Use biometrics' on macOS) to ensure your identity is verified before viewing stored credentials.

    Note: If you do not see the biometric toggle, ensure Chrome is updated to the latest stable release.

    Remove Unprotected Passwords

    Review your browser's password manager for entries that lack strong, unique passwords. Delete any credentials associated with dormant accounts or sites that do not support modern security standards. Consolidate your security posture by keeping only essential, active logins.

    Note: Regular auditing limits your attack surface if your local user account is compromised.

    Disable Browser Password Saving

    For maximum security, disable built-in browser password saving entirely if you use a dedicated third-party password manager. In Safari, uncheck 'Usernames and passwords' under the AutoFill tab. In Chrome, disable 'Offer to save passwords' within the Password Manager settings.

    Note: This forces your Mac to rely on a standalone, encrypted vault for all credential management.

    Secure Your Local Mac Account

    Browser security is only as strong as your Mac login. Navigate to System Settings, click 'Lock Screen', and set 'Require password after screen saver begins or display is turned off' to 'Immediately'. This ensures your browser data is shielded as soon as you step away from the keyboard.

    Note: Always lock your screen manually by pressing Control + Command + Q when leaving your desk.
