Reference from “ I like eating big meat buns ” The comments

You have to have a biological code , It's not realistic to have a password for every website

How unrealistic I just don't have a website and a password

Fixed string AAAA+ The websites + Fixed number 1234, such as

shuaiTencent2000

shuaiNetease8159

shuaiBattle8159

shuaiDouyin8159 

This is not on each site a password on the line , In the face of small websites that may store plaintext passwords , Just use another solution   Fixed string BBBB+ The websites + Fixed number 1234, In this way, there is no need to worry about the disclosure of plaintext passwords , Others see the law and guess the password of my big website
