Description:
Currently, XPipe relies on "Askpass" to prompt for passwords when accessing services like Tailscale. While functional, this approach is outdated and lacks support for modern authentication workflows, such as biometric/pin-based system prompts (e.g., fingerprint scans).

Proposed Change:
Integrate with system-native authentication backends (e.g., GNOME Keyring, KDE Wallet, macOS Keychain, Windows Credential Manager) to securely retrieve passwords. This would:

• Allow seamless use of biometric authentication (e.g., fingerprint scan, FaceID) via the OS.
• Improve security by leveraging established system credential stores.
• Align with UX patterns used by other apps like KeePassXC, Bitwarden, and modern IDEs.
• Eliminate the need for manual fingerprint support implementation in XPipe.

Relevant Examples:

• KeePassXC and Bitwarden both allow the use of system authentication to unlock databases.

This change would simplify maintenance, enhance accessibility, and provide a more intuitive user experience across platforms. Let’s discuss implementation details (e.g., libsecret for Linux, Security.framework for macOS, Windows CredUI) and prioritize cross-platform support!
