It's true -- hackers can get around some types of multi-factor authentication (MFA). And this is scary! MFA has long been touted as the best way to protect your accounts. And this is still true.
MFA is not bulletproof, and certain types of multi-factor authentication are more vulnerable than others.
The type of MFA used is so important, that the CISA recently released guidance about which types are the most secure. This guidance is helpful, and we've taken this information a step further. Below are screenshots of the different types of MFA. You may not have realized there are different types.
These are all real situations that happen more frequently than you might imagine!
Hackers are constantly changing their tactics, and it's important to stay ahead of them as much as possible. It's important to use the strongest types of multi-factor authentication possible. For many, the best MFA is with app-based number matching or app-based/token-based with one-time passwords. If your email is currently protected by MFA SMS codes, we strongly recommend changing the type of MFA, or switching email programs altogether. It's that important!
We loved the guidance from CISA, but made it more user friendly with the infographic below. Seeing the pictures of MFA in action can help you recognize which forms you are using. If you're using mostly SMS or Voice, it's worth looking at stronger options.
For example, if you log into your Facebook settings, you can choose between SMS, Authentication App, or Security Key -- the strongest option is the Security Key, followed by Authentication App and then SMS. Any MFA is better than no MFA, but be sure to check the options!
