I have written before about 2FA/MFA. This article in the Wall Street Journal provides a good 2 or so minute read on one the more popular keys around – The Yubikey and others.

The Strongest Protection for Your Online Accounts? This Little Key – WSJ

I can write all day about physical keys. They provide some real good protection. The article also mentions something important….. a back-up.

I use my 2FA on any and every sensitive account possible. Most of them provide a back-up method if your primary key is lost or breaks. Many time it’s the Authenticator App or SMS, or something. There are many that offer you some one-time codes that work.

Whatever and however you pursue your 2FA/MFA journey, make sure you review your options, as being locked out of your accounts is painful.
