32-bit Password Protection

32-bit password protection provides a basic level of access control by requiring a 4-byte password before write or read operations. Found in NTAG 21x series and MIFARE Ultralight EV1, it prevents casual tampering but is vulnerable to brute-force attacks due to the small key space (2^32 combinations).
