This works; we could alternatively probably just resolve MongoOTPRepository

[shreyamalviya]

We'll have to register MongoOTPRepository in cc/services/initialize.py which doesn't make much sense since we don't need it anywhere else and we want to keep all the authentication hidden in the facade.

Resolve is not the same as register. Calling container.resolve(MongoOTPRepository) should be sufficient.
