Question

I have a module that can be accessed only by admin, except for a single action that can be accessed by all authenticated users.

Is there a way to reset the credential for that single action? I tried to use null but still get 403 Error. Is listing all actions in security.yml the only solution?

default:
  credentials: [ admin ]

public:
  credentials: null

Answer 1

Have you try to set en empty array or credential ?

public:
  credentials: [ ]
