Hi @dmytro_ii,
The best pratice would be to use an API key to connect your Excel and Kobo form, second best is username and password as Authorization in excel. By this way you don’t need to share username and password information with anyone to set-up the synchronization. Also, people can not access the data without username and password though KoboToolBox interface. So you can keep your data safe,secure and private. API Keys are also needs to be secured, but to work with it require experince so not a standart user can do something with it.
