For a more secure password use at least 8 or more characters up to 255. You can use upper or lower case letters (e.g., A-Z, a-z) as well as numbers. You may also add special characters (e.g., !, @, #, $, %, ^, &, *, (, ), _, <, >, ?, etc.) to make your password more secure. You should also never use your username or email address or other passwords from other sites as your password.
