Xfinity Email login history

My email account is set up with 2-step authentication. While I was already logged off my Xfinity email, I received an unexpected authentication code on my other device, which was turned Off. I happened to turn it On about 15 minutes later, which is when I saw the authentication code timestamped 15 minutes earlier. It seemed like somebody was trying to gain access to my email account while I was neither logged in and second authentication device was turned Off.

I suspect this happened because I used a different browser recently, which may have exposed my ID and password credentials I used for logging to my email. As I realized this, I immediately used a different browser to change my email's password. I won't be accessing my email account from that recent browser any longer.

Is there a history report available for Xfinity Email for checking all the email login attempts with timestamps? This would be great to have for detection of potentially compromised credentials.
