# Deep Security Manager REST API

## Path: / rest / authentication / signinastenant / name

Sign in as a tenant, and return a session ID (sID) to use in subsequent calls to other APIs.

Note:

- Sign in as a tenant will not log out the original session
- if your application uses both the SOAP web services API and the REST API, the same session ID can be used in both APIs; you do not need to log in separately to each API.
