Securing your Instagram Account: Advice from the Instagram Help Centre
■ Turn on two-factor authentication ( Settings > Security > Two Factor Authentication) for additional account security.
■ Never give your password to someone you don't know and trust.
■ Think before you authorise any thirdparty app – you should never share your login information with an app that you don't trust. If you give these apps your login information, whether with an access token or by giving them your username and password, they can gain complete access to your account.
■ Pick a strong and unique password that you haven't used for other accounts. Use a combination of at least six numbers, letters and special characters (such as !$@%), and try to avoid repetition.
■ Change your password regularly, especially if you see a message from Instagram asking you to do so. During automated security checks, Instagram sometimes recovers login information that was stolen from other sites. If Instagram detects that your password may have been stolen, changing your password on Instagram and other sites helps to keep your account secure and prevents you from being hacked in the future.
■ Make sure that your email account is secure. Anyone who can read your email can probably also access your Instagram account. Change the passwords for all of your email accounts and make sure that no two are the same.
■ Download your data. You can keep a backup of your data by requesting a copy of everything you've shared on Instagram in a machine-readable HTML or JSON format. Note: You'll need your Instagram account password to request this information.
■ Log out of Instagram when you use a computer or phone that you share with other people. Don't tick the "Remember me" box when logging in from a public computer, as this will keep you logged in even after you've closed the browser window.
