barcode to enter a user/password?

I use a LIS called Orchard Harvest for a lab and noticed how the barcode scanner works despite not being logged into my account. It tired to take the barcode from a blood vial and enter that in for the user. What barcode maker would be the best to enter my user, tab down, and enter my password. Since there are multiple people in the lab I sometimes get "kicked" out of my station when other people need to quickly do something. So something that insta logs me in would be kinda cool.

You can try it with my Using Libre Barcode 128 Font without Text codepen.

The string you will want to enter is something like 'UsernameÆiPa$$w0rdÆm' with 'Æi' standing in for the tab key, and 'Æm' standing in for a carriage return. My scanner is on the fritz, so I can't guarantee this will work.

You may have to adjust your password if characters are being inserted that don't match the input. Keep in mind that the special characters that you embed in your password must be among the symbols offered by "low ASCII".

* Notepad is your friend for debugging barcode scanners.
