Hi there

@TimV's post from a couple of years back is still relevant: [Accidentally deleted .security index for x-pack - #3 by TimV](https://discuss.elastic.co/t/accidentally-deleted-security-index-for-x-pack/69844/3). Note that step 2

> From a security point of view, you now have a "new" cluster, so the reserved users `elastic` and `kibana` will have reset to their default _"changeme"_ passwords.

doesn't apply anymore since we do not have default passwords for the built-in users, but the rest of the instructions are good to go !
