If you’re a Yahoo user, there’s a good chance you’ve used the messaging service to communicate with friends and family. But if you want to delete your account, there are a few steps you need to take. First, open the Yahoo Messenger app on your phone and sign in. Then, click on the three lines in the top left corner of the main screen and select “Delete Account.” Once you’ve deleted your account, be sure to close all of your other Yahoo Messenger apps so that they don’t keep track of your old messages and conversations.
