OTP authorization

One time password (OTP) authorization gives your end users an alternative way to log in to the MinistraPRO application on their device.

Instead of entering a username and password, an end user can enter a unique password that is sent to them by SMS. A new password is generated each time a user accesses the MinistraPRO application on their device, and is valid only for one login session.

For OTP to work, you must have the following:

• An integration with an external billing provider to deliver SMS messages to the user.

• The ability to connect your external billing provider with MinistraPRO's end points for OTP authorization.

The otp_auth_phone.ini file stores the configuration settings for OTP.

otp_auth_phone[api_host]	The URL of the external billing provider.
otp_auth_phone[password_length	The number of characters for the one time password, for example, 6
