rembYou can use an environment variable here
password = "$NPM_PASSWORD"
* * *
Then assign your Azure Personal Access Token to the `NPM_PASSWORD` environment variable. Bun [automatically reads](../../../runtime/environment-variables/index.md) `.env` files, so create a file called `.env` in your project root. There is no need to base-64 encode this token! Bun will do this for you.
.env
NPM_PASSWORD=<paste token here>

To configure Azure Artifacts without `bunfig.toml`, you can set the `NPM_CONFIG_REGISTRY` environment variable. The URL should include `:username` and `:_password` as query parameters. Replace `<USERNAME>` and `<PASSWORD>` with the appropriate values.
terminal
NPM_CONFIG_REGISTRY=https://pkgs.dev.azure.com/my-azure-artifacts-user/_packaging/my-azure-artifacts-user/npm/registry/:username=<USERNAME>:_password=<PASSWORD>

Don’t base64 encode the password
* * *
In [Azure Artifact’s](https://learn.microsoft.com/en-us/azure/devops/artifacts/npm/npmrc?view=azure-devops&tabs=windows%2Cclassic) instructions for `.npmrc`, they say to base64 encode the password. Do not do this for `bun install`. Bun will automatically base64 encode the password for you if needed.
**Tip** — If it ends with `==`, it probably is base64 encoded.
* * *
To decode a base64-encoded password, open your browser console and run:
browser
atob("<base64-encoded password>");
* * *
Alternatively, use the `base64` command line tool, but doing so means it may be saved in your terminal history which is not recommended:
terminal
echo "base64-encoded-password" | base64 --decode
