Why is Comcast often asking me to change my password?

Thanks for reaching out to us, for security purposes you may get notifications to reset or update your Xfinity Wi-Fi password. To verify the devices that are connecting to your home network I recommend jumping on our awesome Xfinity app https://www.xfinity.com/apps going to Wi-Fi details and then devices and remove any devices you're not familiar with

I am in the same boat I am being constantly harrast by Comcast to change my password, getting tired of it, every couple of months. How can I put a stop to it [Edited: "Personal Information"].
