The password field in a Battle.net account does not distinguish between lowercase and uppercase letters

Description: I enter my password, but I write letters of the wrong size, I press “login” and enter my account. Both in the application for the PC and on the website.

PS: Also, I enter my password, then I enter a few extra symbols, and this also does not prevent me from logging into my account.

Reproduce:

  • take an account (account password with lowercase and uppercase letters)
  • open battle.net.exe / go to https://eu.battle.net/
  • Enter login
  • enable Caps lock
  • enter password
  • login to account
