Data Usage for Duo Push Notifications

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 range.

While concerns regarding data usage are understandable, the bandwidth consumed by the mobile app for daily authentication requests has a negligible effect on overall 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 is over 16 authentications per day, which is well above the average usage threshold of even the most frequent users.
