Never re-use your e-mail IDs
When it comes to e-mail, the rule is simple: don't use the same e-mail for all websites.
It is a common practice, but sometimes it can become too convenient. Sharing one e-mail address with multiple sites can make it easy for hackers to get hands-on with your e-mail from data breaches.
This can lead to data leaks and even identity theft—and that's not something we want to happen!

So how can you keep your e-mail account safe? The best way is to compartmentalise your e-mails e.g., One e-mail for social media, One private e-mail for banking and One E-mail for personal use most importantly, for junk website sign-up, try to use burner e-mail services like temp-mail.org/en. This way, one e-mail breach won't impact other compartments.
Be safe out there.
