i try to test the password character limit as much as possible, however, graphics cards have enough computing power to crack passwords in record time. So, one might ask, what can i do to protect my accounts and such from getting hacked? Honestly, nothing. but you can minimize the damage to other accounts by always having different passwords and/or similar passwords for low important accounts. High security accounts should never have the same password, contain letters, uppercase, lowercase, special characters if possible. And for that extra level of security, you can generate specific site-based passwords based on a master password combined with the login site address and hash that into an encrypted password. that way, all you need to remember is the master password. all of your passwords will always be different because the generated hash is different for each site. Therefore, someone hacks your minecraft account, they cant hack any other accounts that use your email address because..... random passwords.
