How to get into an old instagram account without password or email

Tap Forgot password on the login screen. Enter your Instagram username or phone number, then tap Send login link. If you've previously linked your Instagram and Facebook accounts, you can reset your password using your Facebook account by tapping Reset using Facebook.

If you can't regain access to the email or phone number you used to sign up for Instagram, you'll need to log into Instagram and change the email or phone number on your profile with a new email account that you can access.

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.
