how to Use PasswordIdentityProvider.allow_password_change

[CJ-Miao]

got the warning DEPRECATED in 2.0. Use PasswordIdentityProvider.allow_password_change
But I dont know how to revise my server_config .How can i use this function?

[krassowski]

It means that you should replace the reference to ServerApp.allow_password_change (or NotebookApp.allow_password_change if you are migrating from a very old version) with PasswordIdentityProvider.allow_password_change. This must be somewhere in one of your config files, you can find paths for config by running jupyter --paths

I want to connect to Jupyter Notebook on a Remote Server.
My config is as follow :
c.ServerApp.ip = '*'
c.PasswordIdentityProvider.hashed_password = u'argon2:$argon2id$v....(my hashed password)'
c.ServerApp.open_browser = False
c.ServerApp.port = 9999

I run jupyter server and got this.
