INDUSTRY STANDARD ALGORITHMS.

Only approved IP addresses are able to make API calls to access any account.

All PIN codes are generated using the industry standard algorithm RFC6238. 

PIN codes have a predefined expiration time and they are not stored by Messente. 

We prefer Messente because it is very easy to use. But the best thing about it is the transparency --we get a very good overview of how our messages are delivered.
