I’m slowly but surely switching everything I use to FOSS alternatives and after using Gboard for a while thanks to it’s good swipe typing, I moved to OpenBoard for the same reason. Unfortunately, the fact that I can’t auto-fill my password via 1Password is bugging me (on top of less-than-ideal autocorrect). You guys know any alternatives?
You can also try AnySoftKeyboard as well, it works fine with Bitwarden. Also, it has many customization options.
