A password protects the project, not a single link. Once you set it, the link, the QR code and the embed all ask for it. Password protection needs the Corporate plan.

The window then says "A password is set." Nobody can read a saved password, including you. To change it, turn Password protected off, which removes the password. Then turn it on again and set a new one.
On a lower plan, the window shows "Password protection requires a Corporate plan". Turning on Password protected opens a form to contact the 3DtoMe sales team.
When someone opens a protected link, scans the QR code or loads the embed, a Password protected window appears before the project loads:
If the password is wrong, the window says "Wrong password, make sure you entered all the characters correctly". With the right password, the project loads as usual.
Visitors enter the password again each time they open or reload the page.
If your plan drops below Corporate, visitors see a "not found" page. 3DtoMe never opens the project without the password. Removing a password works on every plan. See Whose plan counts.
