Secret Access Link
Create a custom link that will allow people to avoid the coming soon mode. Anyone who accesses your site via this link will be able to see your normal site instead of the coming soon page.
You can customize the link by writing anything you want (since you’re making a secret link, write something that people won’t be able to guess easily), and then click the clipboard icon to copy it.
Your link should look something like this: https://comingsoonwp.com/?your-secret-keyword.
