Hi! 1. We are currently working on the Proton Pass web app. Some users prefer to have native desktop apps, which is why we're looking into developing those too. 2. Proton Pass allows you to generate email aliases (it's one of its core functions), therefore, it needs to be connected to an email account. You however don't need to use this function - you can create a separate Proton account just for Proton Pass, so your main email account wouldn't be connected to your Proton Pass account. 3. We plan to support Passkey in the future. 4. You can set up an account recovery method on your Proton account(s), of course: https://proton.me/support/set-account-recovery-methods.
