The Arc loader has demanded the user have a PIN in addition to the email and password for the site and loader. This is arrogant in the extreme and it means no games will be installed or played. When they come back to their senses I may reconsider their loader.
This is arrogant as secure passwords are available easily with Edge and Chrome. I developed a secure password generator to make sure all sites are unique. Typically 128-bit is all that fits most sites but some can handle 192-bit and 256-bit passwords.
Modern brower can alsoo suggest a secure password but they tend to be 64-bit to 72-bit entropy which is weaker than the FIPS SECRET standard of 128-bit.
SInce browsers cannot handle double passwords the loader is now useless.
