Make password optional
It would be nice if setting the password could be optional.
I think it's a valid use case to only share your project with members who already have an account. In that case you don't need the password. Having to set it could annoy users and will probably lead to users setting weak passwords for the projects. That in turn is bad as everyone, even without an account, can gain access to the project, if he guesses the password and the project id.
