Any security issues with using a font for password input?

Question

I have an app where many users will share 1 PC and log in and out many times per day. In this use case it's imperative that passwords are not saved in the browser. The only way I can seem to totally prevent this is to use an text input and apply a custom font to it where the letters are obfuscated. Am I opening up any security holes by doing this?

You can set autocomplete=none. Password managers should respect that and not save passwords for that field.
