SOLVED!
For anyone having the same login problem with the Zyxel VMG8623-T50B, after a factory reset the password printed next to “Login Password” on the label did not work for me.
The solution was:
Username: adminPassword: Enter the Serial Number (S/N) from the router label instead of the Login Password.
After entering the serial number as the password, I was able to access the router settings.
Hopefully this saves someone else some time.
