After you or your Mac administrator resets the password of your macOS user account, your Mac might ask you to update your keychain password or enter the password of your login keychain. It might also tell you that the system was unable to unlock your login keychain. That's because your login keychain is still using your old password.
After having updated to macOS Catalina, you may get a pop-up window stating “AMPDevicesAgent wants to use your confidential information stored in iOS backup in your keychain” when you backup up your iPhone or iPad. So what is AMPDevicesAgent? Is this something new within macOS Catalina? Nov 17, 2015 I just installed Microsoft Office 360 and every time I use Powerpoint or OneNote or Word its says Microsoft 'whatever program I am using' wants to use your confidential information stored in. Microsoft Office 2016 programs asking to use confidential information stored in my keychain. For your reference: Mac Installation 2016 office.
If you don't know your old password, the solution is to create a new login keychain.
If you know your old password, use that password to update your existing login keychain:

ISSUE
If you use OneNote 2016 for Mac and OneNote for iPhone and iPad, you may be asked to sign in any time you open the OneNote app or when you switch between notebooks. Similarly, OneNote may require you to sign in repeatedly to resolve sync errors.
STATUS: INVESTIGATING
Please update to the latest version of OneNote for Mac, iPhone and iPad. If you've downloaded OneNote from the Mac App Store, launch the App Store and check for Updates. You should see the option to update OneNote there. If you installed OneNote as part of Microsoft Office for Mac, then open OneNote, go to the Help > Check for Updates menu to launch the Microsoft AutoUpdate app and follow instructions there. Update all of the Microsoft Office applications, since they all use the same keychain items. To learn more, see Check for updates in OneNote 2016 for Mac.
To download the latest version of OneNote for iPhone and iPad, check the App Store for automatic updates. If you also have other Microsoft Office apps for iOS (Word, Excel, PowerPoint, Outlook), you will need to update all of them.
If you are still experiencing the issue after installing the recent updates, the next step would be to clear your Office credentials, and recreate them by following these steps:
To clear your Office credentials for macOS
Sometimes your credentials can get corrupted, causing OneNote to continually prompt you to enter your password. To clean this up, do the following:
Quit from all Mac Office Applications, except for OneNote
In OneNote, sign out. This only logs you out, and all the notebooks will still be there.
Quit OneNote.
Launch 'Keychain Access' and search for all items that contain 'Office15'. There should be only a couple items, one for each account you have logged into.
The name will be a long alpha-numeric code and the kind will start with “MicrosoftOffice15…”
Delete these items. It is only deleting the authentication credentials, no data. Once you sign in again, they will be re-created.
Launch OneNote and sign into your accounts.
Since all the office apps share the credentials (Word/Excel/PowerPoint) you will have to sign in again with those apps as well.
To clear your Office credentials for iOS
Sometimes your credentials can get corrupted, causing OneNote to continually prompt you to enter your password. To clean this up, do the following:
If you have other Office apps installed (Word, Excel, PowerPoint, etc), make sure you have updated this to be the latest version. Microsoft outlook mac os x. Since we share the same Office identity, if there is a bug in any of those apps, it can corrupt the identity.
Clearing your credentials often helps. To do that, follow these steps.
Go to iOS Settings > OneNote > Reset OneNote > Delete Sign-In Credentials and turn the toggle on.
Make sure OneNote is not running. (Double tap the home screen to see all running apps and swipe up on OneNote to close it.)
Re-open OneNote and sign in again.
