If you’ve been inactive on your Yahoo account for a while, there are a few things you can do to reactivate it. First, make sure you have your password reset. If you don’t, you may need to change it. Second, check your account settings and make sure that your email and password are both set up correctly. Finally, if you’re using a different Yahoo account for work or school, make sure to update your settings so that your old account is still working as expected.
