This release is a pre-release and may not be stable for production use.
earthaccess-auth
A minimal-dependency distribution containing only the NASA Earthdata Login (EDL) authentication core of earthaccess: login strategies, token lifecycle, per-DAAC S3 credential exchange, and the redirect-safe requests session. Integrations with fsspec and obstore are optional extras, so auth-only consumers install none of the search/download stack.
Motivation
Downstream services and libraries commonly need EDL auth and nothing else from earthaccess. One concrete example from the titiler ecosystem is titiler-multidim, which needs a bearer token string to inject into icechunk virtual chunk container headers. It deploys as an AWS Lambda zip, where earthaccess's transitive dependencies (s3fs, fsspec, python-cmr, pqdm, tenacity, ...) count against the 250 MB unpacked limit for the sake of ~500 lines of auth logic.
Install matrix
pip install earthaccess-auth # requests + tinynetrc + typing_extensions only
pip install earthaccess-auth[fsspec] # + fsspec/aiohttp HTTPS session
pip install earthaccess-auth[obstore] # + obstore credential provider bridge
pip install earthaccess # full stack (does not yet depend on this package)
Example: the titiler-multidim case
import earthaccess_auth
auth = earthaccess_auth.login(strategy="environment")
token = auth.token["access_token"] # inject into icechunk http_store headers
