## Introduction
Returns a set of temporary security credentials that you can use to access MinIO resources. AssumeRole requires authorization credentials for an existing user on MinIO. The advantages of this API are
- To be able to reliably use S3 multipart APIs feature of the SDKs without re-inventing the wheel of pre-signing the each URL in multipart API. This is very tedious to implement with all the scenarios of fault tolerance that's already implemented by the client SDK. The general client SDKs don't support multipart with presigned URLs.
@ -6,8 +24,8 @@ Returns a set of temporary security credentials that you can use to access MinIO
The temporary security credentials returned by this API consists of an access key, a secret key, and a security token. Applications can use these temporary security credentials to sign calls to MinIO API operations. The policy applied to these temporary credentials is inherited from the MinIO user credentials. By default, the temporary security credentials created by AssumeRole last for one hour. However, use the optional DurationSeconds parameter to specify the duration of the credentials. This value varies from 900 seconds (15 minutes) up to the maximum session duration to 12 hours.

## Introduction
Returns a set of temporary security credentials for applications/clients who have been authenticated through client credential grants provided by identity provider. Example providers include WSO2, KeyCloak etc.
Calling AssumeRoleWithClientGrants does not require the use of MinIO default credentials. Therefore, client application can be distributed that requests temporary security credentials without including MinIO default credentials. Instead, the identity of the caller is validated by using a JWT access token from the identity provider. The temporary security credentials returned by this API consists of an access key, a secret key, and a security token. Applications can use these temporary security credentials to sign calls to MinIO API operations.
By default, the temporary security credentials created by AssumeRoleWithClientGrants last for one hour. However, use the optional DurationSeconds parameter to specify the duration of the credentials. This value varies from 900 seconds (15 minutes) up to the maximum session duration to 12 hours.

**Please note that when AD/LDAP is configured, MinIO will not support long term users defined internally.** Only AD/LDAP users are allowed. In addition to this, the server will not support operations on users or groups using `mc admin user` or `mc admin group` commands except `mc admin user info` and `mc admin group info` to list set policies for users and groups. This is because users and groups are defined externally in AD/LDAP.

## Introduction
Calling AssumeRoleWithWebIdentity does not require the use of MinIO default credentials. Therefore, you can distribute an application (for example, on mobile devices) that requests temporary security credentials without including MinIO default credentials in the application. Instead, the identity of the caller is validated by using a JWT access token from the web identity provider. The temporary security credentials returned by this API consists of an access key, a secret key, and a security token. Applications can use these temporary security credentials to sign calls to MinIO API operations.
By default, the temporary security credentials created by AssumeRoleWithWebIdentity last for one hour. However, use the optional DurationSeconds parameter to specify the duration of the credentials. This value varies from 900 seconds (15 minutes) up to the maximum session duration to 12 hours.
