How to recover instagram account without password or email

If you don't remember what email and the phone number you used. Recover Insta account using your username. Tap "Get help logging in" or "Forgot password?" button on the sign-in page and insert your username. The letter with the link or code will be sent to your email.

If your account was deleted by you or someone with your password, there's no way to restore it. You can create a new account with the same email address you used before, but you may not be able to get the same username.
