Is NFC password protection secure?

On NTAG21x, there are 4 bytes allocated to the password.
The range is 00 00 00 00 to FF FF FF FF, which means there are 4 294 967 296 possibilities.
For example, on an NFC reader which takes 200ms to communicate with the chip, it will take approximately 27 years to brute force the password.
