MG90 Password Not Accepted

I am unable to log into on my MG90. Using username admin password admin returns invalid authentication. I tried doing a factory reset - while the flashing lights never turned white as indicated by documentation, they did all flash once then turn off, and then the machine rebooted which I take to mean it did reset. However, after this I still receive the invalid authentication error when attempting to log in. I’m not sure where to go from here in terms of getting access, any advice is appreciated!
