Resetting or changing identity is simple but currently you need to do it outside the Bittorrent Sync client. Stop the clientDelete the folder %APPDATA%\BitTorrent Sync or rename it (i.e %APPDATA%\BitTorrent Sync_IdentityXXX) if you want get it back laterStart the clientSync will create a new folder and it all begins as it was the first time you start the application. When you want to use a new identity or restore the old one, just stop the client, delete or rename back the app folder - saving also the current one with another name if you care - restart the client, and voilĂ . This operations don't affect files inside your local folders and you can share them again using your preferred identity. Please note: in this way you can override the 30 days PRO trial limit so please act fairly.
