No, I assumed that it must be a new feature. Whenever I try to do a concatenating tunnel with a simple string, the wire breaks. Obviously, I am doing something wrong....

(I use the concatenating tunnels for arrays all the time and am aware of that.)

I could never get the hang of the concatenating tunnel for strings either. Seems to be hit-n-miss for me. This particular case does not work in LV2020 for me either.

For me it works with LV2021, but not LV2020 or earlier.  Interestingly it's not mentioned in the What's New documentation for LV2021.

You are right this does not work in LabVIEW 2020 sp1. 

Interesting as I just skimmed the LabVIEW 2021 release notes, bugs fixes, and new features, but I see no reference to this being fixed or feature changed.

Some developer must have just snuck this in?

While we are finding (silly) alternatives, here's another one: 😄

(seems to operate mostly in-place)

 ... and its a great new feature. Very intuitive. I cannot count how many times I tried to concatenate strings using a concatenating tunnel in the past, then just getting slapped with a broken wire instead. 😄

Are you trying to replace the strings or you want to display the string as password??

If you want to display the string (control/indicator) as password you can try below method by just right click.

How to do it programmitically, also instead of * character if I want to use # character how to do that.

You can make your own workaround. ("Key down?" filtering event, store actually entered key and display #, etc.)

(Not sure why you would want to have nonstandard behavior. Just to confuse the user?)
