+The connection string is pre-populated with your SQL username and password, the cluster name, and other details. Save the password in a secure place such a password manager. You can find the connection string at any time from the CockroachDB Cloud Console. You can reset your SQL password for this cluster from the cluster's **SQL Users** page.

+CockroachDB is a [distributed SQL](https://www.cockroachlabs.com/blog/what-is-distributed-sql/) database built on a transactional and strongly-consistent key-value store. It **scales** horizontally; **survives** disk, machine, rack, and even datacenter failures with minimal latency disruption and no manual intervention; supports **strongly-consistent** ACID transactions; and provides a familiar **SQL** API for structuring, manipulating, and querying data.
+
+CockroachDB is inspired by Google's [Spanner](http://research.google.com/archive/spanner.html) and [F1](http://research.google.com/pubs/pub38125.html) technologies, and the [source code](https://github.com/cockroachdb/cockroach) is freely available.
