Jupyter lab prompts for token; how do I find it?

Question

I have Anaconda and just started Jupyter lab. I am prompted to enter my token or password, but I don't know what my token is. Do I have a token? If so, can I find it? If so, how?

Here is the output I got:

You can find ~/.jupyter directory, this should be your home directory. This looks like you already configured your password (which replaces the token), so the output does not contain the token:

[W 2021-02-18 00:38:55.881 NotebookApp] 'password' has moved from NotebookApp to ServerApp. This config will be passed to ServerApp. Be sure to update your config before our next release.

Read more in notebook token documentation and remember to follow the migration guide. Use jupyter notebook password command to change the password.
