(invite_users_to_login)= # Invite users to log in > This task is the responsibility of {ref}`role_project_team`. Users participating in a project that uses an SRE will have been added to that SRE by the {ref}`role_tresa`. The {ref}`role_project_team` should advise the users to follow the Data Safe Haven [User Guide](https://data-safe-haven.readthedocs.io/en/v4.2.2/roles/researcher/user_guide.html) set up their accounts. As documented in the guide, most users short form username will take the form `firstname.lastname`, however some may differ from this convention (for example users with very long names). The {ref}`role_project_team` can check with the {ref}`role_tresa` where this is the case. When users follow the guide, they'll need to know the ``, the `` and the resultant `` for the SRE they will connect to, which will take the form: > `https://..turingsafehaven.ac.uk/` For the `` of the SHM currently set up and used in production see {ref}`current_shm`. The `` will be unique to the project SRE that has been set up by the {ref}`role_tresa` .
