If your Apple TV is asking for a password when using AirPlay, this is likely happening because a new update has just occurred.

Simply take the device you are trying to connect to AirPlay and input the password that shows up onscreen.
To enable AirPlay on your Samsung TV, you will go into the settings of your TV first. To do this, navigate to ‘Settings’ > ‘General’ > ‘AirPlay Settings’ > ‘AirPlay’ > and then turn the AirPlay feature ‘On’ if it has not yet been switched on. Once you have done this, your TV will be in a constant mode to be able to mirror whatever you please without having to enable the feature again.
