While configurable via PASSWORD_SALT_HASH_ROUNDS env var, the default matters because: (1) most deployments use defaults, (2) existing password hashes at 5 rounds remain vulnerable even if later increased. With modern GPUs, 5 rounds allows ~300,000 hashes/second vs ~10,000/second at 10 rounds - a 30x difference in cracking speed. In a database breach scenario, all user passwords could be cracked significantly faster. The same weak default is used in resetPassword (account.service.ts:568).
