Set the preview password
Open the project’s Settings view and find Password. Enter a password between 8 and 128 characters, then choose Set password. Only a workspace owner can set, change, or remove a password.
Check the preview address in a private browser window before sharing it. Send the password separately if that suits your client’s workflow.
Understand review-link access
A review link bypasses the preview password. Its holder can access the reviewed version and use the review controls that link permits. Setting or changing a preview password does not revoke existing review links.
To remove a reviewer’s link access, turn off that link in Review links. The separate preview address continues to follow the project’s password setting.
Change or remove the password
Use Change password to replace it, or Remove password to stop asking for it. Without a password, anyone with the preview address can open the site.
Unlisted previews and requests to search engines not to index them are not access controls. Choose a password when the preview address should require one.
