Currently, Proton Pass (and SimpleLogin) does an amazing job at hiding user emails via aliases. However, most modern services (social media, marketplaces, fintech) require a phone number for SMS verification. This is a massive privacy hole where users are forced to give up their real identity, leading to SIM swapping risks and marketing spam.
Describe the solution you'd like
I propose an "Integrated Phone Alias" system within Proton Pass.
Generation: Users can generate a virtual phone number (VMN) directly from the Pass UI.
Reception: SMS codes sent to that number appear inside the Proton Pass item (similar to how 2FA codes work now).
Recycling: Users can "recycle" (delete/rotate) the number once they are done with a service or if it starts receiving spam.
Describe alternatives you've considered
Using third-party "burner app" services, but these are often untrustworthy, not encrypted, and don't integrate with a password manager.
Additional context
As a College developer and privacy enthusiast, I believe this aligns perfectly with Proton’s mission. Technically, this could be handled by a backend integration with a VoIP provider (like Twilio/Vonage) while the mapping of the number to the Proton account remains end-to-end encrypted in the proton-pass-common logic
