You might need to make one or more of your links only available to a few people. Password-protection allows you to have private links that can only be opened if the visitor knows the secret password.
To password-protect your existing link, follow these steps:
Head over to the Lnks section
Tap/Click on the link you want to password-protect
Tap/Click on Password-protect, as shown below
Type and repeat your password then click Save
All done! Your link is now password-protected
