Password resets as often as daily

I have read through older, closed posts in the community forum.  Just in the past couple of months, I have had to reset my password with increasing frequency, to the point that it is sometimes daily now.  I use MS Outlook on all of my devices, so when the password has to be reset, I have to change it on as many as five different devices, which is becoming quite frustrating.  I have third-party verification set up on my xfinity account.  I am not sending out SPAM emails as some posters have mentioned.  I have had my Comcast.net email address for over 20 years and really do not want to change to another (due to years of accounts tied to that email) , but am considering it if this continues.  Is there someone in the security department that can assist?

Do you have 2FA set up?
