The password field in Dittofi is intended to store private information in a secure way. This field will (generally speaking) be populated by your apps users, by filling in a form, such as a sign up form their frontend.
Note that because your apps users will likely use the same passwords for multiple websites and apps, there are laws around the way password data must be treated by a software company. Essentially all passwords must be salted, hashed and encrypted so that the company that is storing the data is not able to view the passwords. Dittofi ensures that data is securely handled, but, it is down to you to use the Password field for user passwords. See how to create a backend to securely receive user sign up data in our article Login endpoint, action and event.
