I'm not sure if I understand your issue correctly...
You can write a MIFARE Classic card as long as you have the correct key (A or B) and the Access Conditions match. Only people with the right key are able to write to the tag. So it's kind of a password. However, there are tools out there to crack MIFARE Classic keys. If you really want to protect the data of an MIFARE Classic card you have to apply your own layer of encryption/signing.

Hello, I want to set password to protect memory access .Without password anyone can not access whole mifare memory. I know there is key A and Key and Access condition in sector trailer but there is some API It is shows Dump information of whole card using UID and default key. I thing MIFARE Ultralight EV 1 have this facility.we can protect memory access by 32 bit password. I also read mifare classic ,we only make read only.There is no password protection . Thanks Dinesh

There are no such things like passwords for MIFARE Classic. Only the two keys. There is no other protection mechanism. And yes, you can make a tag read only.
