usercode app

A “usercode” is an alpha/numeric code that the user enters when logging on to a protected system.

The RealSender “usercode” app automatically generates a unique user code every hour,
which is sent upon request to the associated email address.

Only pre-authorized email addresses can request the user code.
The length and complexity of the user code is agreed upon during system configuration.

For example, this is the content of the email message that sends the user code:

Your user code is: 665407

!! the user code expires every hour at:03

Integrating with your secure system is simple:

1. we configure the IP address authorized to retrieve the user code
2. you set up a cronjob* that automatically updates the password based on the retrieved user code
   (the update must be performed for each user authorized to access the system)
   * = a time-based task scheduler, used to automatically run commands at specific intervals

To increase security, we recommend enabling “fail2ban” protection,
which blocks visitors after a certain number of unsuccessful login attempts.

You can see it in action by activating a RealSender trial account.
Aong with the data for sending emails, you will receive instructions for accessing your user area.

For example, this is the content of the email message containing instructions
for accessing the RealSender user area and web space:

your user area access link:
https://username:usercode@rsXXX.realsender.com/reserved.area/

your web space access link:
https://username:usercode@rsXXX.realsender.com/view/

!! access links expire every hour at :03

In this case, the usercode is used in a web-based access system protected by “basic auth”.
Both the “username” and “usercode” parameters are automatically filled in,
ensuring the user a simple and immediate access experience.
