As your company's Procore Administrator, your first step is to enable MFA for your entire company and choose an enforcement deadline. This is the mandatory enrollment date for your end users. Once MFA is active in your environment, it is your responsibility to manage resets for users who lose device access. See Reset MFA for a User.
Best Practice: 30-Day Transition Window
Give users 30 days between your announcement and the enforcement deadline. This window lets them set up MFA on their own schedule instead of being forced to do it on a busy day. Share this guide to help them with their first-time setup and subsequent login.
