You can also use temporary email when registering on Twitter, Instagram, Facebook, and other social media sites. However, it is better to register on social media sites with your e-mail address and phone number. Because known and reliable sites like these will not send you harassing or infected emails. In some cases, these sites may need to send you e-mails, if you use disposable e-mails, you will not be able to access the same address again, so you cannot see the e-mail sent to you and you may have problems logging into your account.
