If you’re like most people, you probably delete your Instagram account after a year or two. But if you want to delete an old Instagram account without the password, there are a few steps you can take. First, open the Instagram app and sign in. Then click on the three lines in the top left corner of the main screen and select “Delete Account.” Next, type in your email address and password (if any) and hit “delete.” You’ll be asked to confirm your deletion before it happens. If all goes well, your old Instagram account will be deleted and you won’t be able to access it anymore. If something goes wrong - for example, if someone tries to access your account while it’s still active - then you’ll need to contact Instagram support to get help deleting it.
