It can be done using token.

There are no reason to allow it in core.

You can do it with https://gitlab.com/SondagesPro/coreAndTools/reloadAnyResponse

Thanks for the feedback.

If I've understood correctly, the reloadAnyResponse is a plugin that may be deployed in a LimeSurvey instance.

Is there an easy way to discover whether this plugin has been deployed from the dashboard?

If you don't do it or ask it : it's not here.

PS !: i have to detail the process of Create save form
PS2: i think you can create save information with GUI in 3.X , not possible currently ?

To be clear, I'm referring to a deployment of the open-source LimeSurvey software as a common resource to be used by a specific community. This service is running LimeSurvey Community Edition Version 6.15.11+250909.

Within that deployment, I didn't see any way in which I could invite someone to continue editing an existing response.

I could believe this might be possible using a token, but I don't even find a way to create/request a token to authorise changes to an existing response.

It don't exist currently, I offer an alternative solution using plugin. But you need to setup this plugin yourself extensions.sondages.pro/about/article/install-and-activate-a-plugin-for-limesurvey

I check : seems an integrated solution exist in 2.X version but disappear somewhere.

When edit response via admin GUI : you can create a username/password at same time.
It can be good to have it again.
