Proposal: Enhanced Privacy for Proton Authenticator

We propose a feature to prevent unauthorized data capture of sensitive information within the Proton Authenticator app.

The current state allows third-party apps to capture screenshots, exposing sensitive data like usernames (which often contain email addresses) and other private information.

Proposed Solutions

1. Screenshot Prevention Toggle: Introduce an option in settings to disable screenshots while the app is in use.

2. Username Masking: Implement a default "click to view" functionality for usernames, hiding them from plain sight.

Justification

These features would align with Proton's core values by significantly enhancing user privacy and security. Implementing these changes would reinforce user trust and protect against data exposure from malicious or unintentional screenshot captures.
