Create a strong password comprised of letters, special characters, and numbers

Change your password regularly (especially if you receive a legitimate request from Instagram for you to do so) - Instagram conducts regular security scans and if your login credentials are exposed anywhere online, it'll push you a note to change the login info quickly

Turn on multifactor authentication for added safety

Keep your account email secure

Log out when you're using shared devices

Never share your passwords with anyone and be cautious with sharing info with third-party apps and services
