Hi @Makhija, Priyanka ,
AFAIK currently masking the input parameters in job details is not a supported feature. This is the related feature request which has already been raised in the feedback forum. So if interested I would recommend you to upvote that feature request. In general, Azure feature or product team would check feasibility of a feature request, triage it, prioritize against existing feature backlog, add in roadmap as appropriate and would announce and/or update the related Azure document once a feature request is addressed.
Until the feature request is addressed and implemented, as a workaround, try to avoid having such sensitive information in parameters and instead try to have them as encrypted variable / credential asset.
