Do you use your email account when traveling? Have you ever set up an email account just to use when traveling?
It might be a good idea to create an email account to use only when traveling. This is especially good if you are accessing wifi in an unsecured network.
Something like email@example.com. That way if someone would access that account, it doesn’t contain any personal data, any work or financial data or emails, or anything you don’t want to lose. Be sure to set a password entirely different from those you may already use. And, give that email address to those you want to communicate with while traveling.
