 ```elixir
+# Enables cache on redis for tokens obtained from Auth0.
 config :prima_auth0_ex, :token_cache, EncryptedRedisTokenCache
 
 config :prima_auth0_ex, :redis,
-  # Enables cache on redis for tokens obtained from Auth0. Defaults to false.
-  enabled: true,
   # AES 256 key used to encrypt tokens on the shared cache.
   # Can be generated via `:crypto.strong_rand_bytes(32) |> Base.encode64()`.
