You're thinking of Lotus Notes, a completely different product.

IIRC, originally it echoed one glyph per character typed, but later it definitely echoed 1 to 3 glyphs at random so it wouldn't leak your password length.

The password thing was pretty cool, but it's literally the only good thing about Lotus Notes, which was the most archaic and primitive piece of commercial GUI software I've ever used in 45 years of software experience. I last used it in 2003, and even then its UI was so archaic, it didn't adhere to behaviors (like keybindings, and other basic UI elements) that had been standard since the 80s.

Absolute garbage software.
