When you delete your account, your profile, photos, videos, comments, likes and followers will be permanently removed.
To delete your account:

1. Leave the Instagram app and log into instagram.com from a desktop computer
2. Click your username in the top right and then select Edit Profile
3. Click I'd like to delete my account in the bottom-right corner

For security reasons, we can't delete an account for you. You'll need to be able to log into your account to delete it. If you can't remember your password or username, see some tips for logging in.
Keep in mind that we can't reactivate your account, and you can only sign up again with the same username if it's still available. If you don't want to delete your account but want to change who can see it, you can set your posts to private or block people.

You will need the email address to retrieve your account access.

At the "password reset" page you should place the email address used to register your account.
