I would like to create a check request form but I only want users who either enter a password or whose Google accounts I give permission, to be able to fill out the form. Is this possible?
One idea if this isn't by default would be to embed the form in a web page that is password protected and then never hand out the URL of the form but I am hoping there is something better than that available.
If you have Google Docs account then you also have access to Google sites. Create a Google Sites page and embed your form on it, then set the page permissions to private and enter those email addresses for the people you want to give access to. If they have a Google account, they can log in under their username. If not, they'll have to create an account first.
I've just adapted some trick which is very simple by using Validation option in Text field to check the password which you set it before give it away. For example.
Set a field with user name let them choose from the list you add their name in advance
let connect those name the pagebreak which is on their name
on the page let set a text field and add the pass word to the option in Validation section specify that with Equal (=) only So, if the password they key in is not the same that person can't pass through your form
p.s. Don't forget to mark x in Required Question check box otherwise that person can pass through your form
