# Login

Provide the username and password in a request body to receive a bearer token to authenticate to the API's other endpoints.
For new integrations, use `POST /token/` instead: it exchanges a signed assertion for the same bearer token, so no password is sent.
See [Authentication](/products/partner-api/guides/building/auth).
