They can access the dashboard and see the live data/ status of your sensor. However, they won't have acess to the settings, logs, alarms or any other parts of the cloud. You can delete this link any time you want and the link will stop working. A new link can be generated again if you need to.

2.If you want to share full access to your sensor dashboard in its entirety, you can set a password to the cloud login that you can share with those you want to. They can also login with the primary email and the password.

3.A third, more secure and convenient way is to use Team feature. This is an option available under the advanced package. Like many of the features under advanced options, Team feature is free to use. You can add anyone with an email address to your team. Once they accept your invitation, you can give them access to all or select sensors in your account. You can also control if they have full access or limited (view-only) access.
