I have both the 2600 Router and the 920+ NAS.... When utilizing 2-Factor Security, The NAS has the "One Touch" Sign In Feature (see screen shot) where I get a PUSH Notification and simply Press "Approve" to Sign in.... While the 2600 SRM only gives me the option each time to Manually Enter the 6 Digit rolling code from my Synology Secure Sign In App on my Android..... Does the SRM have this One-Touch Option?
