That is a degenerate argument. an apartment is clearly yours. Without your password there is no way to conclusively prove that a phone is yours. SIM cards can be swapped, for example. The incriminating is not stating the password. it is the fact that you are proving the phone as yours.
Which does not in any way prove that it is yours. Over my lifetime I purchased over 30 phones. Only two of them are currently mine. If you were to place another one I have purchased, but long ago sold in my possession, that would not be enough to prove that it is currently mine. if I happen to know the password, that might be very convincing.
