When you are under the configuration tab for the RV22 home mesh devices, or one of the XV2 AP’s you can see the password for the AP group in clear text under the Default Value section under WLANs in the Advanced Settings.
I think it would be nice to have this hidden to avoid shoulder surfing incase you have different WLANs built for different levels of network access within a company. That way a receptionist doesn’t have the opportunity to look over an engineers shoulder and see the credentials for a WLAN that they shouldn’t have access to.
