 Once you have got an application that is xref:servlet/authentication/index.adoc[authenticating requests], it is important to consider how that resulting authentication will be persisted and restored on future requests.

-This is done automatically by default, so no additional code is necessary, though it is important to know what `requireExplicitSave` means in `HttpSecurity`.
+This is done automatically by default.
+If you have a custom filter or controller that is setting the security context, you will need to use a `SecurityContextRepository` to persist it across requests.
+
+If you are upgrading from an older version, you may be interested in the `requireExplicitSave` setting that preserves Spring Security 5's default, though note that this is primarily for migration purposes.

 If you like, <<how-it-works-requireexplicitsave,you can read more about what requireExplicitSave is doing>> or <<requireexplicitsave,why it's important>>. Otherwise, in most cases you are done with this section.
