Approzium is a tool that provides:

  • Password-less database authentication
  • Authentication through your cloud-provider's built-in identity
  • Highly security-oriented logging and metrics

Its aim is to prevent data breaches, and to help you detect them promptly if they do occur or are attempted.

Please note: We take Approzium's security and our user's trust very seriously. If you believe you have found a security issue in Approzium, please responsibly disclose by contacting us at

See the SECURITY guide for more details.

We currently support AWS for identity, and have a Python SDK for Postgres drivers. This project is under active development, please do stay tuned for more identity platforms, databases, and SDK languages.


See for a Quick Start, or elaboration on the architecture and API.


For questions, please either open a Github issue, or visit us in our public Slack channel.

To visit us in Slack, use this invite. Then venture to # help-and-questions. Our developers frequent our Slack forum, but are not in it at all times. Please be patient, we will lend assistance as soon as we can!


We welcome community contributions!

We use docker-compose.yml to quickly and easily provide you with a development environment that mimics real life. To spin up an end-to-end development environment based in Docker:

  • Ensure you have Docker installed with Buildkit support (Docker 18.09 or higher)
  • In your local environment, run $ aws configure and add an access key and a secret. Also, make sure that you have the AWS_REGION environment variable set, informing the AWS region that will be used. For instance:
export AWS_REGION=us-east-1
  • Then run $ make dev-env. This will build the authenticator and development Docker images. Also, it will run the authenticator with a Vault backend and the test database servers (Postgres and MySQL).
  • In another window, $ make dev. This will start a shell in the development environment.
  • You now have a full development and testing environment!
  • For example, to use our Python SDK to create an Approzium connection to a Postgres server:
    • Create an Approzium path in the test Vault backend: $ make enable-vault-path
    • Give your AWS-identity access to the test server: $ make seed-vault-addr ADDR=dbmd5:5432
    • Create a connection: $ cd sdk/python/examples && poetry run python3


Our end-to-end tests take a few minutes to run. Please run them once locally before you submit a PR.

To run the tests, first you will need to:

  • Create an AWS Role (E.g. ApproziumTestAssumableRole) thats going to be used during the tests.
  • Ensure that you are using an AWS User with at least the following permissions:
    "Version": "2012-10-17",
    "Statement": [
            "Effect": "Allow",
            "Action": [
            "Resource": "arn:aws:secretsmanager:us-east-2:<some-account-id>:secret:approzium/*"
            "Effect": "Allow",
            "Action": "sts:AssumeRole",
            "Resource": "arn:aws:iam::<some-account-id>:role/ApproziumTestAssumableRole"
  • Set the AWS_REGION and the TEST_ASSUMABLE_ARN environment variables, for instance:
export AWS_REGION=us-east-1 && \
export TEST_ASSUMABLE_ARN=arn:aws:iam::<some-account-id>:role/ApproziumTestAssumableRole

Then, to run the end-to-end tests, from our home directory:

  • Run make test. That's it!
