  • Setting up and using Multi Factor Authentication (2FA/MFA)
    What's wrong with my username and password? Typical online authentication requires a username and a password – this is something a user has to know. These can be (and are frequently) written down, shared with other people or leaked from hacked sites to the world by malicious third parties.. Users will often setup the same username and password with multiple online services.

In theory, the only passwords you ever need to remember … Read more

It means you can log into your bank, your online shopping, your mailbox and social media without having to remember dozens of passwords. However, using the same password on multiple online services is like using the same key to unlock your front door, your car, your suitcase and your safety deposit box. If someone sees your key and makes a copy of it, they can now unlock everything. They can not only steal whatever you're protecting with that key (money, personal information etc), but they … Read more
