Two Factor Authentication

Why 2FA is Important

An Added Layer of Security for Accounts

A strong password is not enough.  Adding an extra step using a 2FA key will make it much harder for people to access your accounts.

The 2FA key or password is often generated by a second device that people need to have physical access to.  Like a smart phone with the 2FA software or USB 2FA hardware key.

There are many variations of 2FA key generators and lots of research is always good to understand the Pro’s and Con’s that work for your personal situation best.

Warning

Like many of these tools, it is important to know how they are backed up and how those backups are stored, so if there is a problem, you are not locked out of your account.
