Since emailPasswordEnforcementState values are restricted, I think you can combine all this to a single if statement.

if (typeof options. emailPasswordEnforcementState !== 'undefined' &&
        options. emailPasswordEnforcementState !== 'OFF' &&
        options. emailPasswordEnforcementState !== 'AUDIT' &&

      throw new FirebaseAuthError(

The reason for this separation is to align with the backend error-code and keep consistency with the existing error message. E.g. empty string is an INVALID_ARGUMENT but invalid string is an INVALID_CONFIG.

The SDK shouldn't allow empty strings in the request to the BE service so this error technically should not occur (from the backend). I felt like the check is redundant because you check for a restricted set of strings here regardless. Not a big issue so I will leave it up to you to decide the best path here.

ManagedRuleAuth.validate(managedRule);
