Hello,
I have a non-standard question. Where can I find information regarding the maximum length of the login and password when creating an account (+ allowed characters)?
While I don’t think it is documented anywhere externally, you can find such information within the code itself.
It looks like the max length for battle net emails is 320 characters
While BNet password is 16 or 128 characters depending on the SRP version being used.
It also looks like the SRP_OLD version only allows Basic Latin (UTF8) characters and the newer SRP does not have that limitation.
