To clarify, an alias is a randomly generated email address that forwards emails to your main inbox. Proton Pass creates aliases so you can enter them into online forms and protect your actual email address from being disclosed or leaked.

That said, we are currently working on integrating the SimpleLogin alias management feature directly into Proton Pass. Once this feature is released in a future update, users will be able to manage their aliases more easily without needing to switch back and forth between Proton Pass and their SimpleLogin accounts.

Hopefully, this clarifies things further. If you have any additional questions, feel free to contact us using the 'Feedback & Help' option.
