What Happens If I Delete ".erlang.cookie" File of Rabbitmq? - rabbitmq

Question

I accidentally deleted the ".erlang.cookie" file in $HOME on one of rabbitmq cluster nodes.
I found that the cluster status is ok and rabbitmqctl cli works well.
It seems that deleting the cookie file is not a problem but I can not be sure that the cluster is really ok.
so I'd like to know whether the deletion I describe above could be no problem.
please help me, I would take any advice gratefully.
additional info
there are 3 nodes for rabbitmq cluster.
all of them have the same ".erlang.cookie" file in /var/lib/rabbitmq/ , but they have different ".erlang.cookie" file in $HOME .
and the file I accidentally deleted was in $HOME on node1
rabbitmq.conf:
[
{rabbit, [
{cluster_partition_handling, autoheal},
{default_permissions, [<<".*">>, <<".*">>, <<".*">>]},
{default_vhost, <<"/">>},
{log_levels, [{connection,info}]},
{mnesia_table_loading_timeout, 10000},
{tcp_listen_options, [
binary,
{packet, raw},
{reuseaddr, true},
{backlog, 128},
{nodelay, true},
{exit_on_close, false},
{keepalive, true}
]},
{default_user, <<"nova">>},
{default_pass, <<"hq33cCIU">>}
]},
{kernel, [
{inet_default_connect_options, [{nodelay,true}]},
{inet_dist_listen_max, 41055},
{inet_dist_listen_min, 41055},
{net_ticktime, 10}

The RabbitMQ team monitors this mailing list and only sometimes answers questions on StackOverflow.
RabbitMQ and its associated commands use the cookie file in /var/lib/rabbitmq. Deleting the file in $HOME will be fine.
