One phone. Two jobs.

Secure storage

Secure storage. Turn the phone you already own into a wireless speaker and microphone for your Mac or Linux computer.

Why CastSound needs secure storage

When you sign in to CastSound Pro on your computer, the app keeps your sign-in session and license in the secure storage built into your operating system. This keeps you signed in and protects your license. The Free tier works without secure storage, so you can keep using CastSound even if none is available.

Linux

CastSound needs a Secret Service provider to store your Pro sign-in session. Install GNOME Keyring for your distribution, then restart CastSound and try signing in again.

Debian or Ubuntu
sudo apt install gnome-keyring
Fedora
sudo dnf install gnome-keyring
Arch Linux
sudo pacman -S gnome-keyring libsecret

On KDE, KWallet provides the same service, so you can use it instead of GNOME Keyring.

macOS

Keychain is built into macOS. Restart CastSound and try signing in again. If it still does not work, open Keychain Access and check that the login keychain is unlocked.

Windows

Credential Manager is built into Windows. Restart CastSound and try signing in again. If it still does not work, check that the Credential Manager service is running.

You can always continue with the Free tier — signing in is only required for CastSound Pro.
