comment How to set and read an NTAG213 with a password?
Both are possible, transceive() works the same for both.

comment How to set and read an NTAG213 with a password?
I suggest you have a look at the NTAG213 datasheet at nxp.com/documents/data_sheet/NTAG213_215_216.pdf. You will find that chapter 10 contains all the details, e.g. from section 10.7 you can derive that you send new byte[] {0x1B, p[0], p[1] ,p[2], p[3]} (without any CRC as that will be supplied by Android) to do password authentication (p[i] are the 4 password bytes).

You would use the transceive() method and pass any password-related command as byte array. The MifareUltralight class only contains helper methods for commands that are common to all MIFARE Ultralight tags.
