+The above link will tell PowerSchool that a parent is authenticating, so it can take them directly to the /public login page. You can also allow for longer authenticated sessions by adding a `remember` query variable with a truthy value, such as `1` or `true`. By default, it is `false`. For example:
+
+```html
+<a href="/auth/powerschool/oidc?remember=1">Sign in with PowerSchool</a>
