Such as "Proton Password," "Main Password," "Primary Password," etc.

Resoning:

The term "master password" has become frowned upon in some contexts due to its historical connotations and the potential for misinterpretation:

1. Historical Connotations: The term "master" has origins linked to dominance, control, and even slavery in some contexts. While this isn't the intention when used in technical contexts like "master password," many organizations and individuals are choosing to avoid terms that might evoke such associations to promote inclusivity and sensitivity.

2. Modern Inclusivity Trends: Many industries, particularly tech, are reevaluating language that could unintentionally reinforce outdated hierarchies or exclusions. Alternatives like "primary password" or "main password" convey the same meaning without potentially problematic undertones.

3. Misinterpretation: For non-technical users, the term "master password" might be unclear or intimidating. Clearer terms like "main password" can help ensure users understand its importance and purpose.

This shift aligns with broader efforts to use language that is clear, inclusive, and free from potentially negative connotations.

This could also tie in better with the use of the additional password phrasing.
