Install CREVO as a real app on your computer — its own window and icon, no browser tabs. It is a one-time install: the app always runs the latest CREVO automatically, so you never need to download updates.
If a blue “Windows protected your PC” screen appears, click More info, then Run anyway. This happens once, only because the installer is distributed privately instead of through a store.
If macOS says the app “cannot be opened”, open System Settings → Privacy & Security, scroll down and click Open Anyway next to CREVO. Also a one-time step.
Your login, 2FA and data work exactly as on the website — the desktop app is the same secure CREVO in its own window. If a download link does not work yet, the installer has not been published — ask your administrator.
