# IT4I Account
-## Obtaining Authorization
-
-The computational resources of IT4I are [allocated][r] by the Allocation Committee to a Project investigated by a Primary Investigator. By [allocating the computational resources][r], the Allocation Committee is authorizing the PI to access and use the clusters. The PI may decide to authorize a number of their collaborators to access and use the clusters to consume the resources allocated to their Project. These collaborators will be associated to the Project. The Figure below is depicting the authorization chain:
-
-
-
-!!! note
- You need to either [become a PI][1] or [be named as a collaborator][2] by a PI in order to access and use the clusters.
-
-## Authorization of PI by Allocation Committee
-
-The PI is authorized to use the clusters by the allocation decision issued by the Allocation Committee. The PI will be informed by IT4I about the Allocation Committee decision.

-## Process Flow Chart

-This chart describes the process of obtaining login credentials on the clusters. You may skip the tasks that you have already done. Some of the tasks, marked with asterisk (\*), are clickable and will take you to a more detailed description.

CESNET, CERIT-SC, and IT4I infrastructures will operate a joint e-INFRA CZ infrastructure. If you have a CESNET (e.g. MetaCentrum, DÚ) or CERIT-SC account, make sure to choose the same login name for your IT4I account to have uniform access to all services in the future.

-!!! warning
- **Only** for those who already have their IT4I HPC account. This is a preferred way of granting access to project resources. Please, use this method when possible.

-* **Users:** Please, submit your requests for becoming a project member.
-* **Primary Investigators:** Please, approve or deny users' requests in the same section.

-## Authorization by EMail (An Alternative Approach)
-
-In order to authorize a Collaborator to utilize the allocated resources, the PI should contact the [IT4I support][a] (email: [support\[at\]it4i.cz][b]) and provide the following information:
-
-1. Identify their project by project ID.
-1. Provide a list of people, including themself, who are authorized to use the resources allocated to the project. The list must include the full name, email and affiliation. If collaborators' login access already exists in the IT4I systems, provide their usernames as well.
-1. Include "Authorization to IT4Innovations" into the subject line.
-
-!!! warning
- Should the above information be provided by email, the email **must be** digitally signed. Read more on [digital signatures][4] below.
-
-Example (except the subject line which must be in English, you may use Czech or Slovak language for communication with us):
-
-```console
-Subject: Authorization to IT4Innovations
-
-Dear support,
-
-Please include my collaborators to project OPEN-0-0.
-
-John Smith, john.smith@myemail.com, Department of Chemistry, MIT, US
-Jonas Johansson, jjohansson@otheremail.se, Department of Physics, RIT, Sweden
-Luisa Fibonacci, lf@emailitalia.it, Department of Mathematics, National Research Council, Italy
-
-Thank you,
-PI
-(Digitally signed)

-## Change Passphrase

-On Linux, use:
-
-```console
-local $ ssh-keygen -f id_rsa -p
-```

-On Windows, use [PuTTY Key Generator][6].

## Certificates for Digital Signatures
We accept personal certificates issued by any widely respected certification authority (CA). This includes certificates by CAs organized in [International Grid Trust Federation][f], its European branch [EUGridPMA][g] and its member organizations, e.g. the [CESNET certification authority][h]. The Czech _"Qualified certificate" (Kvalifikovaný certifikát)_ provided by [PostSignum][i] or [I.CA][j], which is used in electronic contact with Czech authorities, is accepted as well.

Web-based email interfaces cannot be used for secure communication; external application, such as Thunderbird or Outlook must be used. This way, your new credentials will be visible only in applications that have access to your certificate.
-## End of User Account Lifecycle
-
-A user account that is not attached to an active project is deleted 1 year after the last project expires to which it was attached.
-
-The user will be notified by 3 automatically generated emails of the pending removal:
-
-* First email will be sent 3 months before the removal
-* Second email will be sent 1 month before the removal
-* Third email will be sent 1 week before the removal.
-
-These emails will inform about the projected removal date and will prompt the user to migrate their data.
