Is account registration or sign-in required to use Keyboard Extension?

No account needed for basic features.

You can use the basic features of Keyboard Extension without creating an account.

However, to create your own widgets and plugins, you'll need to register and sign in. Signed in users also get access to additional widgets and plugins.

Once you sign in, you’ll be able to use the Widget Editor, integrated into the mobile app, to design and customize your own layouts. You will also be able to upload Autohotkey scripts and convert them into Autohotkey plugins which can then be used for widgets.

Registration only requires an email address.
