Definition

Usage & Nuances
"Backdoor" is both literal (physical door) and figurative, common in tech as 'backdoor access.' In IT/security, often refers to hidden entries created by hackers or software. Don't confuse with 'back door' (space), which can also describe the physical door—'backdoor' (one word) more often means the hidden/secret sense. Formal and informal contexts.
