Staying-revealed fields get concealed on holding Ctrl+Alt.

Hello again jinux_go,

On the other hand, it is hard to imagine that a user want to hide passwords briefly.

While the option to hold Ctrl + Alt is enabled, this acts as a toggle and depends on the current state of that field and if it will be either revealed of concealed.

Based on your preference, the best use cases here are to enabled Always show passwords and full credit card numbers and disable Hold Ctrl + Alt to toggle revealed fields. Or, if you are concerned with the possibility of shoulder surfers, I recommend always concealing passwords/credit cards and enabling Hold Ctrl + Alt to toggle revealed fields as mentioned for those times you may want to briefly look at passwords.

I hope this this helps, but do let us know if you have any other concerns.
