I try to login to cli tool bw.
After I login with “bw login”
I get .
You are logged in!
To unlock your vault, set your session key to the `BW_SESSION` environment variable. ex:
$ export BW_SESSION="null"
> $env:BW_SESSION="null"
You can also pass the session key to any command with the `--session` option. ex:
$ bw list items --session null
I try to understand what is problem.
