    For some reason beyond my knowledge my phone lock screen changed from a pattern to a pin. Lucky I remembered my backup pin as I would have otherwise had no clue how to get into my device 'Samsung S6'. After getting into my phone and going to "settings->lock screen and security->Screen lock type" all but the PIN and Password options were grayed out. Including the 'None' all stating "disabled by adminitrator, credentials...". After going on some other forum pages I saw that many people with similar problems went to 'clear credentials'. So I did and it was grayed out also. After doing the typical turn it off and on again trick I then went to 'settings -> lock screen and security -> other security settings -> Device administrators' and deactivated ALL of them (I had email and android device manager). This WORKED! woohoo! I was worried I would have to factory reset!

    My issue now is I am not sure what reactivating the android device manager will do... and the option to reinstate the email one is gone....

    Help

    Google's Android Device Manager is standard and good to leave on

    www.google.com/android/devicemanager

    It can locate, lock or wipe your phone remotely.

    With the email security if it's work or exchange email you may need to re-install it, or it may ask to be set again, not sure
