Not on the client-side! Sometimes it happens when you're typing the first char, in which case you can hit shift (which is visibly activated) and then type the char. But sometimes it 'autocorrects' when you hit the return key, and the only workaround I've found is to type the password with the first char doubled, and then go back and delete the first of the doubled chars. Not fun, especially when you're navigating the cursor on a touchscreen!
