Time Investment Required

Core Strategy Overview

The approach is built on four key principles designed to create defense-in-depth for digital identity:

Foundation Elements

Technology Stack

Core Services

Hardware Security

Security Note: Always purchase YubiKeys directly from Yubico or authorized resellers, not from third-party marketplaces like Amazon. This reduces risk of receiving tampered or counterfeit devices.

Implementation Strategy

Phase 1: Account Audit & Migration

Begin with comprehensive cleanup of existing digital footprint:

Phase 2: Secure Email Foundation

Establish encrypted, obscure root email infrastructure:

Phase 3: Alias Management System

Create scalable email alias infrastructure:

Phase 4: Password Manager Integration

Centralize credential management with strong security:

Phase 5: Multi-Factor Authentication

Implement layered authentication across critical accounts:

Security Benefits

Security vs Privacy: Understanding Trade-offs

Important Distinction: This guide prioritizes security over privacy:

Privacy Compromises Made

Practical Compromise Strategy

This approach acknowledges that perfect privacy is impractical for most people's real-world needs. The setup provides "practical security with reasonable privacy" by:

Real-World Limitations

Email Reply Complexity

Challenge: Replying to emails sent to aliases requires using SimpleLogin's outbox system, which can be cumbersome for ongoing conversations.

Workaround: Use Gmail/traditional accounts for job applications and recruiter communications where frequent email replies are expected. Use dedicated Proton Mail aliases for services requiring frequent interaction.

Alias Management Discipline

Challenge: Reusing aliases across services defeats the isolation purpose. If the same alias is used for multiple services and one shares your email, spam source becomes unclear.

Best Practice: Always use unique, service-specific aliases even for similar purposes (e.g., siteA-newsletter@domain.com, siteB-promo@domain.com).

Disaster Recovery Planning

Critical Balance: The more secure the setup, the easier it is to lock yourself out permanently.

Recovery Mechanisms

Testing & Maintenance

Cost Analysis

Key Insights

Security Through Compartmentalization: The core strength of this approach is isolating compromise to individual services rather than allowing cascade failures across entire digital identity.

Practical Security Philosophy: Perfect security that nobody can use is worthless security. This setup balances strong protection with real-world usability requirements.

Graduated Response: Not all accounts need maximum security. The system allows different security levels based on account importance while maintaining overall protection.

Living Document: Security requirements evolve. This guide represents current best practices while acknowledging ongoing refinement needs, particularly in disaster recovery planning.

Implementation Status

This guide reflects active use and real-world testing of the described security strategy. Areas for continued development include disaster recovery procedures, family/household implementation strategies, and enterprise integration considerations.

The approach has successfully prevented credential stuffing attacks, simplified breach response (immediate alias identification), and significantly reduced spam through email isolation while maintaining practical usability for daily digital activities.
