How much data does a Duo Push request use?

Duo Push authentication requests require a minimal amount of mobile data – less than 2 KB per authentication. This amount of data usage falls well within a "typical" push notification. While concerns regarding data usage are certainly understandable, the bandwidth consumed by Duo Mobile for many authentication requests every day would have an overall negligible effect on mobile data use. For example, you would only consume 1 megabyte (MB) of data if you were to authenticate 500 times in a given month. That's over 16 authentications per day, which is well above the average authentication threshold of our most aggressive users.
