Incorrect login credentials
For Proton Mail Bridge on Linux, we support a range of [secret-services], e.g. GNOME keyring(new window) or a range of password managers, e.g. Pass(new window) or KeePassXC(new window). If you don’t have any of those, you might need to setup your account every time you start Bridge, as your vault would be locked and not accessible to the Bridge app.
For any other error that prevents you from logging in, please contact our Customer Support team(new window).
