SourceControl (SVN) ask password many times.


I want to use Source Control (SVN) function that built-in UE4.
So, I opened Source Control (SVN) setting dialog.
I input provider, repository, user name, labels directory and password.
Then I click “OK” button.
[Connect Source Control] banner was displayed.
But then, if I do something, I will be asked for my password many times.
If you know how to avoid this, please tell me.

Thank you.
