Hi @kiris05
Welcome to community.
To confirm, this is only happening through the Sonos app, and your password for Pandora is being auto filled into the password field? Auto-fill for passwords is usually an OS level feature that we aren't able to override. Unfortunately, our ability to troubleshoot the Sonos app is limited. If it's only happening when using the Sonos app, if you haven't already, I would try uninstalling/reinstalling the app to see if it would help improve the experience.
Let me know how it goes.
