Proton Pass could benefit from the ability to export to KeePass .kdbx to ensure both security and data sovereignty. The current unencrypted CSV export is a plaintext risk that compromises all credentials if the file is lost or stolen. The KDBX format, however, provides robust, file level protection through AES-256/ChaCha20 encryption and HMAC data integrity checks. Furthermore, KDBX is also an industry standard, structured format that preserves your entire vault's metadata, grouping, and custom fields, allowing for a non lossy, seamless migration to offline applications like KeePassXC, which is vital for users managing highly sensitive information.

Overall, Protonpass is great for organizing, securing, and creating a majority of my logins (especially handy with simplelogin integration). Though, some of us also rely on Keepassxc for more sensitive information and offline use cases.
