TortoiseHG comes with Pageant which is an SSH authentication agent. You load your keys into Pageant and it automatically authenticates you so you don't need to enter your passphrase. Do the following to load your keys:

1. Start Pageant by double clicking its icon.
   By default, TortoiseHG installs the Pageant in the C:\Program Files\TortoiseHG folder. When it is running, Pageant appears in your system tray:

1. Double-click the Pageant icon to launch the Pagent Key List dialog.
2. Click the Add Key button.
   The system displays the Select Private Key File dialog.
3. Navigate to and open the default key you created previously.
4. Enter the passphrase when prompted:

1. Press OK.
   Pageant shows your key in the running list.
2. Press Close to close the dialog.
   Pageant continues to run on your system.
