The use of the same login name and password for access to different accounts and websites is strongly discouraged. If a website that you visit is compromised, the attacker will have access to the login names and passwords that were used.
If this website’s login name was your email address, the attacker now has that piece of information. If you used the same password as your email account, the attacker now has access to your email account, all the personal information contained within, and even the ability to reset passwords for other sites.
There are several secure password apps available that do a good job of providing tracking and securely saving login names and passwords. A search of the App Store will give you some to research. We recommend: Keeper Password Manager & Digital Vault by Callpod. We will followup with a more detailed message on this type of app.
For added security on your Nipissing email account, consider enabling 2-step verification. 2-Step Verification adds an extra layer of security to your Google Account, drastically reducing the chances of having the personal information in your account stolen. To break into an account with 2-Step Verification, one would not only have to know your username and password, they would also have to have your mobile phone.
