Custom Redirect

I am trying to create a page similar to the wp_login page. Where there are 2 fields, A “username” field and a email field (the email field is saved and recorded for marketing purposes), attached to this page I want a 2 column table (column A consist of a list of “usernames”) & (Column B consist of the links the “usernames” redirect to, all these usernames redirecting to different links”. The purpose of the table feature is so I can continuously add “usernames” and the links they redirect to as needed. The function im looking for is when customers go to this page, they can type their code “username” in the first field, and there email (similar to a registration) in the second field. The email is saved to a seperate table or spreadsheet and the user is redirected to a specific page based on the code they typed in the first field. you can also think of it as logging into a subscriber page with no password, the subscriber page as the substitute for the code “username” Can someone help me with this? https://wordpress.org/plugins/redirect-by-custom-field/
