Do you experience the same on other music services?.Is there someone else who knows your Pandora account?.To help you out with this, let me ask a few questions. If you're being prompted an error as access denied, this means that there's a problem with your account. The Sonos app validates your Pandora account and music subscription. Sonos doesn't save, change, or reset the password of any music services accounts added in the Sonos app. Thanks for reaching out to the Sonos community and for letting us know about your concern.
