1.  Please make sure you have inserted the microSD card into your phone. The microSD 
card password option will only be displayed when an microSD card is inserted. 
2.  If the microSD card has been inserted, please check whether the microSD card is set 
as the default storage location. If it is, please change the default storage location to the 
phone's internal storage. (Reason: when the microSD card is set as the default storage 
location, your phone will recognize it as internal storage, where the microSD card 
password is not applicable.) 
3.  After you've done all of the above, please enter Settings > Advanced settings > 
Security > Set SD card password to set your password.
