Qcm Locker (PassCode Control)

Qcm Locker helps QcmMaker authors protect portable .qcm quiz files before they are shared. Create a lock, generate PassCodes, protect the file, and keep control over who can open your content.

- Create locks for quizzes, exams, courses, or training packs

- Generate PassCodes for learners, customers, or selected groups

- Set optional expiration dates and usage limits

- Protect .qcm files while keeping normal file sharing simple

- Copy or export access codes when you are ready to distribute them

- Disable a lock to stop future access when needed

- Sign in with Google to manage your locks from one account

Qcm Locker is built for teachers, trainers, schools, and professional quiz authors who need more control than a plain shared file can offer. Share your quiz normally, but let PassCodes decide who gets access.
