Block page
You can display a custom block page when users fail to authenticate to an Access application. Each application can have a different block page.
To create a custom block page for Access:
- 
In Zero Trust ↗, go to Settings > Custom Pages. 
- 
Find the Access Custom Pages setting and select Manage. 
- 
Select Add a page template. 
- 
Enter a unique name for the block page. 
- 
Select Failed identity provider check. 
- 
Copy the Required script. 
- 
In Custom HTML, enter the HTML code for your custom page. For example, <!doctype html><html><body><h1>Access denied.</h1><p>To obtain access, contact your IT administrator.</p></body></html>
- 
To check the appearance of your custom page, select Download and open the HTML file in a browser. 
- 
Once you are satisfied with your custom page, select Save. 
You can now select this block page when you configure an Access application.
