Support Azure Entra ID (Azure AD) token-based authentication with auto-refresh

[glm2bg]

Hi,

I’m working with Azure Cache for Redis and Microsoft Entra ID (formerly Azure AD) authentication. Azure supports connecting to Redis using Entra access tokens instead of a static password. These tokens expire after ~1 hour and require automatic refresh.

Currently, ioredis only supports static connection strings/passwords. This makes it difficult to use with Azure Entra ID, since we’d have to manually recreate the client whenever a token expires.

Feature request:

Add support for token-based authentication for Redis when using Azure Entra ID.

Ideally provide a way to plug in a token provider (e.g., from @azure/identity or MSAL) so ioredis can refresh the token automatically before expiration.

Use case:

Applications connecting to Azure Cache for Redis using enterprise authentication (Entra ID) instead of static keys.

Frameworks like @fastify/redis rely on ioredis internally, so this feature would enable ecosystem-wide adoption.

References:

Azure docs: Authenticate with Microsoft Entra ID to access Azure Cache for Redis

Would this be considered for future support?

Thanks!

@glm2bg In case you weren't aware, node-redis supports Entra ID. Consider migrating, as it's the most actively maintained Redis client for js/ts.

@bobymicroby I am using fastify-redis which is a wrapper around ioredis and i want to keep using fastify-redis, there is no possibility for a migration at this time
