There are multiple ways for signing into the application. After launching the client, the login screen on the left will be displayed. You can sign in by entering your username and password and clicking Sign In. If you are using our mobile application, you can also sign in by scanning the QR code you received from your project's manager. Simply click Scan QR code to start scanning. Please note, that logging in via QR code is not available for the offline version of our mobile client. If you wish to be kept logged in to the application, you should enable Keep me logged in before signing in. That way, you will only have to enter your login credentials once.
