Sorry. What does "MFA" mean? And what does "...MFA fired..." mean? Thank you.

ETA: For those who didn't know, such as myself: "Multi-factor Authentication (MFA) is an authentication method that requires the user to provide two or more verification factors to gain access to a resource such as an application, online account, or a VPN." One of my banks has it, but I didn't know the term. Sorry again.
