I need to tighten access to my admin panel by adding two-factor authentication. The flow should prompt users for their usual credentials and then send a verification code to the email address already stored for that account. A standard, no-frills email template is fine; the priority is reliability and security, not custom branding. when i change password it does not force apk to log out 1. i already have admin panel where i can add more user 2. i have admin back end panel where i change password and crm apk 3. my code is on php i have back end code
