Users must change their password every day to sign in

Hi charlieTRNZ, 

Thanks for posting and welcome to the Community Forum. 

I understand having this error message every time a user logs in would consume time. I'm sorry to hear about the error message. I would suggest clearing the browser data first. Here are the steps. 

1. Go to the control panel of your computer. 
2. Select internet options. 
3. Click delete browsing history and cookies.
4. 
5. Select the options in the next screenshot. 
6. 
7. Click delete. 
8. Click the settings in the general tab. 
9. 
10. Click view files. 
11. 
12. Delete all contents in the folder. 
13. 

After following these steps, you can try to log in to see if the error persists. 

Let us know if you require any further assistance with this. 

Cheers,
