Admin is locked out

Hello, today a writer for the blog received an email asking to “VERIFY YOU LOGGED IN TO…” and when I tried to log in as the admin, it told me I needed to reset my password. Upon attempting that, it says that admins can’t do that.
So, I disabled the plugin via FTP by renaming the folder.
I could easily delete and reinstall the plugin to regain functionality, however, I want to know if there’s a way to fix this so I can find out why I was locked out. Last I knew the plugin was keeping track of stats, the last thing I wanna do is delete that precious data. What should I do? Thanks!
