# Testing your connection

Last validated Jan 5, 2026

Try these steps to check if your connection is working.

## Add more nodes

Once you're sure that your first Tailscale node is working, we encourage you
to activate Tailscale on more devices and test that they can connect to each
other.

All the devices where you log into Tailscale with the same account (such as a
`@gmail.com` account) or with an account in the same organization (like
`@tailscale.com` or `@example.com`) can access each other. If you want to
restrict access between devices, you can use [access control policies][kb-access-control].
