Proton Pass 1.42.0 — the first minute without a single click
How we tested: a clean Debian 13 in a disposable container; source — official file https://proton.me/download/PassDesktop/linux/x64/ProtonPass.deb (proton-pass 1.42.0). Run as a regular user on a virtual screen, 60 seconds, nothing clicked. 18.10.2026. Every network request and every file written was recorded; the code was not decompiled. The container was deleted afterwards.

A DNS lookup is not yet a connection: the program looked up the server’s address. But the lookup itself is visible to the ISP and the DNS server.

How to read this card
- This is the first minute after launch with no action at all: what the program does on its own. Normal use may involve more requests.
- A “built-in SDK” means the library’s code was found. It does not prove data transfer, and an address in the code is not a request.
- The review was made automatically using a single method. You can check any program yourself here.
