Hello everyone,
With the today’s Patch 2.6.10, Diablo III in-game account log in has been updated to allow a password exceeding 16 or more characters. Thank you for waiting on this update!

Hello,
We’re afraid to say that we need to push back our deployment schedule for Diablo III in-game account log in with a password exceeding 16 or more characters. Currently we’re targeting October window, and we will let you know more if there is any progress.
Thank you for your patience and understanding!
If your password exceeds 16 characters following this update, you will be able to log into and play Diablo III through Battle.net, but will not be able to log into Diablo III in-game at the account login screen until June 9.
Hello everyone,
To increase account security, we’ll be updating Battle.net on April 15 to allow your account password length to exceed 16 characters, the previous limit. However, it is crucial to note that Diablo III does not support passwords that exceed 16 characters.
We are already planning ahead to resolve this issue as quickly as possible, and plan to have a patch out that addresses this on June 9.
If your password exceeds 16 characters following this update, you will be able to log into and play Diablo III through Battle.net, but will not be able to log into Diablo III in-game at the account login screen until June 9 .
Thank you for your patience as we work on a solution. We’ll see you in Sanctuary!
