## Using cloud authentication with Redis {% new_in 3.13 %}
2+
3+
Starting in {{site.base_gateway}} 3.13, you can authenticate with a cloud Redis provider for your Redis strategy. This allows you to seamlessly rotate credentials without relying on static passwords.
4+
5+
The following providers are supported:
6+
* AWS ElastiCache
7+
* Azure Managed Redis
8+
* Google Cloud Memorystore (with or without Valkey)
9+
10+
Each provider also supports an instance and cluster configuration.
11+
12+
{:.warning}
13+
> **Important:** {{site.base_gateway}} open source plugins do not support any Redis cloud provider cluster configurations.
14+
15+
To configure cloud authentication with Redis, add the following parameters to your plugin configuration:
16+
17+
{% navtabs "providers" %}
18+
{% navtab "AWS instance" %}
19+
20+
You need:
21+
* A running Redis instance on an [AWS ElastiCache instance](https://docs.aws.amazon.com/AmazonElastiCache/latest/dg/auth-iam.html) for Valkey 7.2 or later or ElastiCache for Redis OSS version 7.0 or later
22+
* The [ElastiCache user needs to set "Authentication mode" to "IAM"](https://docs.aws.amazon.com/AmazonElastiCache/latest/dg/auth-iam.html#auth-iam-setup)
23+
* The following policy assigned to the IAM user/IAM role that is used to connect to the ElastiCache:
