Credential Store

Mac OSX

Passwords are stored in the OS X Keychain.

Linux/Unix

If running, GNOME Keyring is used, otherwise qtkeychain tries to use KWallet (via D-Bus), if available.

Windows

By default, the Windows Credential Store (aka Windows Credential Locker) is used (requires Windows 7 or newer). Pass -DUSE_CREDENTIAL_STORE=OFF to cmake use disable it. If disabled, QtKeychain uses the Windows API function CryptProtectData to encrypt the password with the user's logon credentials. The encrypted data is then persisted via QSettings.

Freedesktop
