After windows update, for some reason I have to keep re-entering remote server passwords whenever I start intelliJ and work on a remote server. This did not happen before. Before this problem happened, I only need to enter the password once, save it, and it would not ask the password ever again. It automatically accessed the remote server smoothly.
Settings-Appearance & Behavior - System Settings - Passwords
Clear after clicking the gear icon button.
After doing this, I entered remote server passwords once and it did not ask again.
