# Settings Security Features

## Summary
Implement security features for the settings editor to protect sensitive information.

## Description
This task focuses on adding security features to the settings editor to protect API keys, tokens, and other sensitive information stored in the .env file.

## User Story
[US001 - Environment Settings Editor](../userstories/done/US001-Settings-Editor.md)

## Technical Requirements
- Implement masking for sensitive values (API keys, tokens, passwords)
- Add functionality to toggle visibility of masked values
- Create a mechanism to detect sensitive values automatically
- Implement warnings when editing critical settings
- Add confirmation dialogs for sensitive operations
- Ensure sensitive data isn't exposed in logs or error messages

## Implementation Plan
1. Create a pattern detection system for sensitive values
2. Implement masking for display of sensitive values
3. Add toggle functionality for showing/hiding sensitive values
4. Create warning dialogs for editing critical settings
5. Implement secure input for sensitive values
6. Add confirmation requirements for changing sensitive settings

## Definition of Done
- Sensitive values are properly masked in the UI
- Users can toggle visibility of masked values
- Critical settings are protected with warnings and confirmations
- Sensitive data is not exposed in logs or error messages
- The system can detect common patterns for sensitive information

## Dependencies
- Rich library for formatted output
- Questionary for interactive input
- Task 001 (Settings Editor Implementation)
- Task 002 (Settings Editor UI Components)
