I decided to try Ubuntu touch on my computer for the first time ever today following This Post's answer as instructions. After running ubuntu-emulator run --scale 0.75 just_testing in around 3 minutes, the terminal showed ubuntu-phablet login:. I did not set any type of password or user so it must be something default right?
The username is
phablet, you don't need to enter a pin if you did not set it. You can change that in the settings or when creating a new emulator.
