Dear Proton Team,

The massive usage of online shopping causes big issues : we all rely on these platforms to secure personal information, and avoid having them available on dark web (or directly sold to date brokers)

As we can hope (or pray) that's the case for Payment info, we all know that "less valuable" info like mobile phone or postal address are not so protected.
And each day i read in the news about a new site leaked by some hacker group (especially here, in France)

So my idea is : instead of filling mobile and postal adresse on each shopping site, i would like to provide a "proton id wallet" link or Id to each site.
Kind of what's it's done when i pay with Paypal, but for administrative information.

From the vendor site perspective, they only have an IdKey, and they have to connect to this ProtonWallet to get the needed information (and they should need it only to send the products)

From the user perspective, i have a dashboard with an entry for each vendor.
And on each entry, i can choose which information i accept to share (the information consent could be configured the first time i do the connection on the vendor site). And i could optionaly set a deadline and/or revoke access.

This new app could have a default "relaxed" behaviour to have more easy adoption for most users (consent for all information requested by vendor with no deadline). Even with this relaxed mode, it would be really more difficult for hackers to leak this information (as they would not be directly in the vendor database)

So besides the technical aspect, the bigger issue is the adoption on the platforms side : more easy for them to keep their system as it and store information locally.
That's why it can be only a serious and big company like you that could propose this. If more and more users install it and ask their favorite platform to move to it, it could change progressively. And marketing campaigns would help ("serious online shops take care of your private data by using Proton ID Wallet")

Thanks for reading me
Julien
