Creating a Password Entry in Google Forms

Process:

By default, a Google Form is accessible to anyone that has the link to it. However, there is a way to restrict access to the submission of the Form by adding a "password" into the Form itself. Doing so will restrict the people able to fill it in and submit, to those that have the password.

To do this, you'll need to split your Form into separate sections (in this case 3, but 2 would be the minimum).

Section 1 contains the title or introduction to the Form and is nothing but a section, title and description:


Section 2 is where the password comes in.

Again, create a new Section and call it "Password". Add a small description to this, such as "Please enter the password to continue".

Add 1 question to this section, make it "Short answer text"
Click the 3 dots in the bottom right of the section and select "Response Validation"
You'll be presented with the following:

Now select "Regular Expression" from the first dropdown and "Matches" from the second.

In the next box, add the password you want entered, and in the last box, the text to display if the wrong password is entered:

Finally, make sure "Required" is selected

Put the remainder of the Form/questions into Section 3.

Now if a user finds the Form, they will be asked to enter the password at section 2 and failure to do so means they will not be able to move on:

This will prevent those without the password submitting the Form.
