Display messages when users sign in
You can insert a page with a message for your users before or after the sign-in page. For example, you can use the pre-sign-in message for a legal warning and the post-sign-in message to notify them of planned maintenance.
The page will display the message you type in, and a Proceed button like the example below.
If you check the Display account activity after sign-in check box, the account activity will appear after sign-in. The screenshot below shows an example where both the account activity and a post-sign-in message are displayed.
Note: The changes will take place immediately.
