First, if you use a weak password, hackers can easily guess it and break into your accounts. For example, passwords like “123456” or “password” are very easy to crack. Also, if your email or social media account is stolen, thieves may send fake messages to your friends or even steal money. Therefore, always use a mix of letters, numbers, and symbols to create a strong password. Remember to use different passwords for different accounts. 1 学科网（北京）股份有限公司 $
