To store your cert and password, all you have to do is:
1. Go to .subversion in your home folder
$ cd ~/.subversion2. Run below command. This command will add store-auth-creds = yes and store-passwords = yes to your bottom of config file
$ echo -e "store-auth-creds = yes\nstore-passwords = yes" >> config3. Run any svn command, and choose p for permanent accept certificate, and yes for storing your password.
Now you won't be asked for svn password anymore.
