I would like to know if it is possible that different users that I have in LimeSurvey can only see the surveys in which they are registered, or only those surveys that they own.

How can I do it?

In admin part or public part ?

In admin part : it's already the case.
Public part : must construc a survey management page : www.limesurvey.com/customization

It's on the administration part, but I don't know how to do it. I have created several users, but when they enter with their username and password everyone can see everyone's surveys.

How can I indicate that a user only sees their surveys? Is there a user administration manual?

Thank you.

How did you set the user permissions?
Two examples:

I give you an example of one of the users:



If I put the permissions as in your examples that user would only have access to their surveys?

In the fourth row you give this user the permissions to

view, edit and delete surveys of OTHER users.

So, empty it

But these are things you just should try to find the best settings or your needs.
Create yourself as a new user and play around with the settings.
