+# Access Secrets In A Rails 5.2 App
+
+For a long time the access chain for getting at secrets in your Rails app
+stayed the same. For instance, getting at the `secret_key_base` value looked
+something like this:
+
+```ruby
+Rails.application.secrets.secret_key_base
+```
+
+In the world of Rails 5.2, secrets are no longer secrets. They are now
+credentials. This means they are under the `credentials` key instead of the
+`secrets` key. Here is how you can access `secret_key_base` now:
+
+```ruby
+Rails.application.credentials.secret_key_base
+```
