2. Confirm the package’s integrity. You can verify its checksum on Debian and Ubuntu-based distros with the following command:

echo "<SHA512CheckSum> ProtonAuthenticator.deb" | sha512sum --check -

On Fedora and Red Hat-based distros, run:

echo "<SHA512CheckSum> ProtonAuthenticator.rpm" | sha512sum --check -

To find the SHA512CheckSum for the latest version of this package, open this JSON file(nuova finestra) in a text editor.

3. Open a terminal window in the directory you downloaded the file to (typically ~/Downloads). On Debian and Ubuntu-based distros, run:

sudo dpkg -i ProtonAuthenticator.deb

On Fedora and Red Hat-based distros, run:

sudo dnf install ProtonAuthenticator.rpm
