- Supports automatic credential refresh methods for various AWS services:
  - STS
  - ECS
- Supports custom authentication methods for complicated authentication flows
- Natively supports all parameters supported by `boto3.session.Session`
- Tested, documented, and published to PyPI

## Recognition, Adoption, and Testimonials

[Featured in TL;DR Sec.](https://tldrsec.com/p/tldr-sec-282)

[Featured in CloudSecList.](https://cloudseclist.com/issues/issue-290)

Recognized during AWS Community Day Midwest on June 5th, 2025.

A testimonial from a Cyber Security Engineer at a FAANG company:

> _Most of my work is on tooling related to AWS security, so I'm pretty choosy about boto3 credentials-adjacent code. I often opt to just write this sort of thing myself so I at least know that I can reason about it. But I found boto3-refresh-session to be very clean and intuitive [...] We're using the RefreshableSession class as part of a client cache construct [...] We're using AWS Lambda to perform lots of operations across several regions in hundreds of accounts, over and over again, all day every day. And it turns out that there's a surprising amount of overhead to creating boto3 clients (mostly deserializing service definition json), so we can run MUCH more efficiently if we keep a cache of clients, all equipped with automatically refreshing sessions._

## Installation

```bash
pip install boto3-refresh-session
```

## Usage

```python
import boto3_refresh_session as brs

# you can pass all of the params associated with boto3.session.Session
profile_name = '<your-profile-name>'
region_name = 'us-east-1'
...

# as well as all of the params associated with STS.Client.assume_role
assume_role_kwargs = {
  'RoleArn': '<your-role-arn>',
  'RoleSessionName': '<your-role-session-name>',
  'DurationSeconds': '<your-selection>',
  ...
}

# as well as all of the params associated with STS.Client, except for 'service_name'
sts_client_kwargs = {
  'region_name': region_name,
  ...
}

# basic initialization of boto3.session.Session
session = brs.RefreshableSession(
  assume_role_kwargs=assume_role_kwargs, # required
  sts_client_kwargs=sts_client_kwargs,
  region_name=region_name,
  profile_name=profile_name,
  ...
)

# now you can create clients, resources, etc. without worrying about expired temporary 
# security credentials
s3 = session.client(service_name='s3')
buckets = s3.list_buckets()
```
