If you use an application that requests your e-mail, do not use the same e-mail as e-mail on other sites. especially social media sites do not create passwords that are easy to hack like birthdates try to fill the password there are numbers, uppercase or small, and punctuation which need to be aware if other people have your private key. And remember that private key can not be replaced. so try to save well and do not let others know your private key.
