How do I connect to my roku stick with out the original remote and I forgot the password
Until Roku updates their firmware-and-apps so that these units work like a IoT smart device, you'll have to buy/borrow/steal a Roku remote to help get past this one.
For best results once you've got a remote, make sure the unit has power and use something to depress the reset button. Then you can just follow the setup routine to get back into your account. After that, you can use the smartphone app to control your unit.
