Want to know the last time a user logged in to your Knack app?

This feature is usually implemented to keep track of the users who use the application, especially the period of time in which a session lasts.

Knack applications allow you to implement authentication forms simply and quickly, however when establishing a control or audit on the logins or log outs that are constantly running within the application, you must resort to the help of JavaScript for that end. Below we list a series of steps that will serve as a guide for the implementation of these logs:

1. Create a new object in the database: Although the object can have any number of fields, it is recommended that it have at least three fields: Email, Date / Time and Action (Multiple Choice = Login or Logout).

2. Add the following lines of code within the API & Code section:

And on this object you can use different native Knack components such as tables, reports or graphs.

We’re sure this will come in handy on all your projects.
