Where Does Proton Pass Store Local Data?
Proton Pass local vault cache and settings per OS and browser.
Last updated
Proton Pass keeps an encrypted local vault cache plus settings in per-OS app folders and browser extension storage, with servers holding the authoritative copy. Wiping local data signs you out but never deletes the vault.
Export recovery kits before device wipes, not app caches. Encrypted caches decrypt only with your account keys.
Where Proton Pass stores this, by platform
%APPDATA%\Proton Pass
Desktop cache with encrypted vault snapshots and settings. Browser extensions store their own copies under each browser profile. Sign back in to rebuild after deletion.
~/Library/Application Support/Proton Pass
macOS desktop cache mirror. Same sign-in rebuild behavior as Windows.
~/.config/Proton Pass
Linux desktop cache tree. Browser extension data stays inside browser profiles, not here.
