what is AMPDevicesAgent

Lay,

AMPDevicesAgent

Here are the basic answers:

• AMPDevicesAgent is not 3rd party software and it is not caused by a virus (or malware). Actually it is included with macOS Catalina. Apple introduced this with Catalina so it is new:

(/System/Library/PrivateFrameworks/AMPDevices.framework)

• You can check this by going to Activity Monitor, it will show up as an Apple process.
• This notification is normal, it is expected behavior and you may enter your password. This should not be a cause for concern. When you enter your password, an unknown third party will not have your sensitive info. if your mac is trusted, you may want to check Always Allow.
• This new AMPDevicesAgent is apart of the Frameworks in your Library folder to allow Finder to synchronization and backup with iOS & iPadOS devices. Basically, AMPDevicesAgent is a new device manager. It is used for backing up, restoring and updating your devices.
• This may appear:
  • When you sync your devices over Wi-Fi
  • When you connect your iPad or iPhone for the first time to your Mac with a USB cable.

If you do not know your keychain password, do not worry, the keychain password is your login password. You can always change this by going to System Preferences > Security and Privacy > General. And then click the Change Password button.
