There is no such flow available as of now but I do have an idea. This may takes a few days to understand if possible
We do have something similar but I think your requirement is to open internet for a while so they can gather their credentials

my Quick thoughts on possible flow that might work
I was thinking if we could take the self-reg success page with login and embed some static credentials then I could make this flow work. This flow is to have self registration with timeout so user can get internet and check email for credentials. User is tied to email address for tracking.
1. User comes in registers for account
2. Credentials emailed and or SMS to used
3. User clicks sign on from self-registration success sign on page. This sign on has static credentials instead of the actual credentials
4. User is logged into guest flow
5. After time user is kicked out
6. Logs in with actual credentials
7. Remember me flow in place to not require further login
Static user guest type with another endpoint group. Or endpoint group for internal endpoint groups.
No registration of endpoint on initial flow
When users logs in 2nd time gets put into guest endpoint for remember me
Authorization if guest endpoints then permit access
Authorization says if temp account guest flow then permit access 10 min. Coa disconnect in the authorization profile.
If mab then redirect to guest portal
Here is the scripting used:
Please find the script for Login and Self-Registration Success pages optional content 2.
For more information working with javascript check out how to work with customization
Login Page
===========
<script>
var successPage;
var gName;
setTimeout(function() {
if(successPage && gName != null){
successPage = false;
document.getElementById('user.username').value = "guestuser";
document.getElementById('user.password').value = "guestpassword";
$('#ui_login_signon_button').click();
}
}, 100);
</script>
Self-Registration Success
========================
<script>
setTimeout(function() {
successPage = true;
gName = $('.ui_self_reg_results_username_label').find('.ui-block-b').text();
}, 100);
</script>
