The existing notes field is useful, but sometimes sensitive information should not be displayed in plain text.

I would like Proton to introduce a “Secret Notes” field type, where content is hidden by default (similar to how passwords are handled).

Example use case: Storing 2FA recovery codes.

Currently, each code would require a separate “secret” single-line field, which is cumbersome. With secret notes, multiple codes (or other sensitive information) could be stored securely in one hidden, structured field.

This would improve usability and security, while keeping entries more organized.
