Serverless Stack

in SST, i know that we can use `auth.attachPermissionsForAuthUsers([api]);` when creating the sst.Auth() constructor. but what if i want to reference an existing already provisioned cognito userpool?

Not sure but you could check if this works :-
```const awesomePool = cognito.UserPool.fromUserPoolId(this, 'awesome-user-pool', 'us-east-1_oiuR12Abd');

new Auth(this, "Auth", {
  cognito: {
    userPool: {
      userPool: awesomePool,
    },
  },
});```

You can also import via ARN. -  <https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_cognito-readme.html#importing-user-pools>

you’ll need to import cognito as such :-
```import { aws_cognito as cognito } from 'aws-cdk-lib';```

I’m assuming you’re on sst version &gt; 0.59.0

Actually currently u can’t pass an existing user pool into `Auth`. <@U033P8AB20L> are you blocked by this? Let me know and I will add support for it.

oh, it’d be great to have this. I would be needing this when I begin switching to cognito from auth0.

<@U01JVDKASAC> it does make attaching permissions to the sst.API instance difficult.

for my current stack, i made a Cognito userpool via the AWS console vs the CDK or sst.Auth constructor

Got it guys. I will take a crack at this and release tonite.

Hey guys, you can now import existing User Pools in v0.66.0. Here’s an example <https://docs.serverless-stack.com/constructs/Auth#importing-an-existing-user-pool>

<@U01JVDKASAC> is it in any relevant to be able to import an existing identity pool as well? I don’t know and so I’m asking.

Ah yeah.. that makes sense. Lemme know when u need to do that, I will put it in.

Sure, thank you, that’d be great. :grin::pray:
