@LeonW Nope, that’s not possible with PBIX, passwords are not safe and most of them can be easily broken, that’s why you have Power BI service for collaboration.
Tested the method noted in the LinkedIn article and it works just fine.
Kindly note that my customer does not want to use this method for data security / data protection or collaboration - That is what the Pro/Premium service is there for, as noted by @AntrikshSharma
