Can customer update their own information if it is Online secured form

I understand that you have this online secured form feature. But, does it mean that user :

• will login to enter data into a form , say form A.
• can login again to form A in order to retrieve their own current user data.

Greetings,

I quite didn't understand your query, can you please elaborate more? if what you're asking is if it's required to log in to a JotForm account in order to fill out a form, not at all times actually, the only time the user is required to create/login an account is if the form is set as private.

can login again to form A in order to retrieve their own current user data.

No need to log in for them to check their submission, you can simply set an Autoresponder email on your form, wherein users will receive a notification email of their submission.
