I was unable to login to beta client while I was able to login to KR, 2d client and account management website. After weeks of searching for solution and asking help from Chrissay, no solution could be found. Today I went at it again and I discovered that while account management, 2d client and KR will accept password of 17+ character length, SA beta client will only recognize password with 16 character length max. My old password was 17 characters and when I changed it to 16 characters I was able to login. While the account management page does ask the password length to be 4-16 characters long, it will still take password that is longer than 16 characters.
