email login failed

[ras_oscar]

Recently I was notified by xfinity that my email password had been compromised and that I needed to reset it. I did so by logging in to my email using my browser shortcut and reset the password. All is well. I have the Xfinity app on my android phone and use it regularly to browse my email. However., I regularly get a message that my xfinity login failed. I assume that somewhere on my phone there is an app that has stored the old password. How do I get more information on which app's login has failed?
