CI -jenkins forgotten password

1. Turn on user authentication

 

 

 2. What should I do if I forget the password after the user registration is completed?

After entering the directory, edit config.xml

 

<useSecurity>
..
...
..
</securityRealm>

 

Delete the codes of the 2 tags, then restart jenkins, everything is back to the past, use it directly without a password;
