We know that it’s not easy to remember such a long and unique password, but you can use a password manager like “1Password” or “Last Pass” to securely store your passwords. You can even store your passwords Chrome Browser, but it’s a risk of losing data if you delete or uninstall it. So, storing the password on cloud password managers is the safe way, and it will always be available when you need it.

Tips 2: Change Your Password Periodically

Changing your password often can improve the security for any services.

So it is recommended to change the password periodically to secure your email service from fraudulent use.

The hacker can use the same password and might be username on multiple profiles as Brute-force attack and can take over on your various accounts


In the past, we saw that many people victimised by hackers with taking over on their Facebook and Instagram accounts due to the same email address and password used for both social media profiles. So best to keep a strong and unique individual password for every account.

Tips 4: Enable Two-Factor Authentication

Two-Factor Authentication (2FA) assuring the right people have got access to the online account. 2FA is commonly used nowadays by many industries like banking, social media platforms and other online services. Sometimes, the service provider has their own way for two-factor authentication such as SMS/OTP, Email Verification Links, Physical Key and some more. But all these methods aim to protect the client’s account and provide them as secure service as they can.

Enabling 2FA (Two-Factor Authentication) uses any two verification methods to access the related email account. Once you get verified with both ways, you can enter to the email client and send or receive emails. Nowadays, cloud email service providers like Microsoft and Google, forcing people to use 2FA for a good reason. It’s a sure-fire way of email or any online accounts security. Make sure you don’t handover your OTP or Email Verification Link access to anyone.

Did you notice those phishing emails that have various links asking you to verify your account? Another example of a phishing email is one that has smartly morphed pages that looks like Facebook or your Bank Institution. Once you open the link, it asks you to log in to that page with some random URL like my-facebook.com. Once you try to log in on that Facebook login page, booooom! Hackers now have your original Facebook login details, and you will notice unusual activities on your social media account straightaway.

Similarly, your bank asking you to log in ASAP to stop your account to being blocked due to fraud money transactions.
