The Remember Me function allows users to add an option that allows credentials to be remembered across different forms and landing pages across the domain the form has been assigned to.
Adding it to your form
1. Access the editing section of your form under the Creatives tab, scroll down and click Add Field as shown below.
2. Under the Type drop down, select Remember Me. 
3. You can edit the text beside the Check box, as well as the message deployed when the Remember Me function is enabled, by clicking on the Edit Options tab under the Input Label section, as shown below.
How long will the user credentials be stored?
As default, the Remember Me function will store and transfer credentials for 30 days, after which the details will be forgotten. This can be changed by accessing the Enterprise on the Convertr platform, clicking on the Configuration tab, scrolling to the bottom and editing the number in the Remember Me For X Days section.
