## Remarks

Used by M-Files components; applications should use
[GetVaultSessionInfo](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCLogin/GetVaultSessionInfo/index.md) and the `session_data`
returned at login instead. Requires a vault session. The RPC binding fields are left empty.
