Can anyone remember the Default to stop MacOS from pre-populating the username whenever an authentication dialog box is presented (ie, i want it to be blank)? I've done it before but can't for the life of me remember the Default or plist where this is located :/
Question
Disable pre-populating username in authentication dialog box

+24I didn't think something like that was even possible. The only time I've ever seen an auth dialog be blank for the username was when the account you're running in is non-admin. If the account has admin rights the OS automatically puts in the username and requests the password. Are you sure you've been able to affect this behavior in the past with a defaults command?
+3Yeah definitely done it before, and fairly sure it was a defaults command. I certainly scripted it, put it that way.
+11If the Security Server can't find the cached creds, it will populate a dialog box, but by default on all seats with admin rights the Security Server will look for cached creds(including globally or via Smart Card)... @mm2270 is correct about if the account is a non-admin, the Security Server can't obtain the cached creds from that account, which would display a empty dialog box... But maybe THIS will be able to help with what you're trying to accomplish
