Purchasing DUO Telephony Credits
Once this is complete, you’ll see an option to add credits:
Duo debits your telephony credit balance for each authentication call or SMS message sent (as per the rate card).
If you ever exhaust your telephony credit balance, your users will not be able to receive authentication phone calls or text messages. They will still be able to authenticate using non-telephony methods: Duo Push, Duo Mobile passcodes, and hardware tokens. Duo Push and Duo Mobile-generated passcodes — are app-based and have no telephony cost, but require a smartphone or other mobile device.
NOTE: When using the DUO mobile app – Telephony credits are not needed.
