Is there a way to use an account for FileVault2 volume-decryption without logging it on? I recall a key-combination, in a pre-Mavericks OSX, that could be pressed after entering one account's info for initial startup FileVault volume decryption. The key-combo prevented a full login of that account, instead dropping again to the login prompt, for login via another account. 

However, I can no longer find any reference to this capability, nor re-discover the combination through trial-and-error. 

Does this option still exist? It was convenient. 

(Of course, I can immediately log-off that FileVault account. But in addition to that extra step, when next logging-into my real work account, I never get the question that allows cancelling the annoying re-opening of all apps open at the last crash.)
I'm not aware of the key-combination.
However, here's how I did this on Mavericks (10.9.2):


Click System Preferences
Click Users &amp; Groups
If the Lock icon is closed, click the lock icon and authenticate
Click Login Options
Locate Network Account Server and click Edit (if there is a network server) or Join (if there is not)
Click Open Directory Utility
If the Lock icon is closed, click the lock icon and authenticate
Click Directory Editor icon
Search for the user you want to restrict
Click the user name
Expand Authentication Authority
Click the + - to the right of Authentication Authority, not the one at the bottom of the window!
Change new value to ;UserDisabled;
Click Save


The user can unlock the FileVault, but cannot login.
