Tired of seeing this window pop up, and having to enter your password every time you use an app? But don’t want to open up all your apps for use?
Here’s a nice and easy fix for you, launch the Keychain Access application (/Applications/Utilities/Keychain Utility) locate the entry relating to the application you want to always allow. In this case, it’s Microsoft Messenger for Mac, double click on the entry to bring up the details window:
Now, select the “Allow all applications to access this item.” click on the save changes button, and enter your password when prompted. You should now find you will no longer be prompted to enter your password when using this application.
NB: The above method comes with it own pit falls, obviously this will now allow anything to have access to this keychain data without prompting you. Bear this in mind when you are authorising items.
