Documents: 

{ "_id" : ObjectId("58ec890c91b2b612084fd827"), "username" : "zain", "passwrod" : 123, "password" : 8 }
{ "_id" : ObjectId("58ec8918364116187845948d"), "username" : "bob", "password" : 123, "passwrod" : 12 }

Query:

db.collection.updateMany({}, {$unset:{"passwrod":1}})

Result:

{ "_id" : ObjectId("58ec890c91b2b612084fd827"), "username" : "zain", "password" : 8 }
{ "_id" : ObjectId("58ec8918364116187845948d"), "username" : "bob", "password" : 123 }
