What do I do if I have upgraded to the ios9 beta then down graded and my device is not accepting my applied password and is requesting the code which I am not getting on my trusted device.
Two factor authentication
Hi Tasha,
You need to turn it off using the link at the bottom of your enrollment confirmation email.
I've highlighted the relevant section from the TFA Support page for you:
"Can I turn off two-factor authentication after I have enrolled?
During the public beta, you will be able to turn off two-factor authentication using a link at the bottom of your enrollment confirmation email. Clicking the link will restore your Apple ID to its previous security settings, including your previous security questions. This link will be active for two weeks after you enroll in two-factor authentication. Please note that your enrollment confirmation email may be sent to your Apple IDemail address or your rescue email address."
