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).

32-bit key space allows brute-force in approximately 4 billion attempts. Password transmitted in plaintext over the air interface. Susceptible to eavesdropping attacks.
