unbypassable
Must go through
Unbypassable describes something that cannot be circumvented or avoided—a barrier, requirement, or obstacle that must be confronted directly.
The security checkpoint is unbypassable; everyone gets scanned.
The word emphasizes that no workaround exists, no shortcut is possible.
More commonly expressed as "impossible to bypass" or "unavoidable," but unbypassable has technical currency in computing and system design where certain processes or validations are mandatory.
