Songspace now offers the option to protect your pitches with a password. You can't set a password for all of your pitches as each password is pitch specific.
If you don't know how to create a pitch link, click here to find out.
There are two ways to set a password on your pitch:
1. While creating a pitch, you can set the password by switching the Require password toggle on by clicking it and entering a password in the field that appears.
2. You can also set a pitch password when editing a pitch in the Settings tab of the pitch edit modal.
