I am working on a custom signup proces, where user first sign up with their name and email and after that they gonna add their company (a post in post type 'companies').
After they have signed up with their name and e-mail the receive an e-mail with a registration link. I need to save their data temporary, so if they click the link, their name and e-mail be retrieved back from the database.
What is the best option to save this data a Wordpress way. Use option table?
I cannot save it in Session because some people read their e-mail a week later for example.
