<a name="Concepts.RDS_Fea_Regions_DB-eng.Feature.IamDatabaseAuthentication"></a>

By using IAM database authentication in Amazon RDS, you can authenticate without a password when you connect to a DB instance. Instead, you use an authentication token. For more information, see [IAM database authentication for MariaDB, MySQL, and PostgreSQL](UsingWithRDS.IAMDBAuth.md). 

IAM database authentication isn't available with the following engines: 
+ RDS for Db2
+ RDS for Oracle
+ RDS for SQL Server
