 Caution: user_sql does not recreate password salts, which imposes a security risk. 
 Password salts should be newly generated whenever the password changes.
 
+Supervision can be enabled under supervisor settings. Supervision allows one
+specified user to login into any account. Use supervisor username and target 
+username separated by ';' to login as target user using supervisor's password 
+(ex. superuser;user).
