If the home directory is not automatically listed as a drive you may add it manually.

In that case you must first log in to the → Virtual Private Network (VPN) of the university before you can connect the personal home directory as a drive.

A small window will now open in which you enter your (Attention: Even if you are a student, there is no 'students' in your name in this case). The password is the password of your JGU account. Close the window with OK.

If you want your home drive to be automatically reconnected the next time you log on, please tick the box next to "Reconnect on logon".

Now click on Finish. You will now find your home directory under the letter selected above under "Computer".

By using the Webdav protocol you may very easily access the files in your home directory via an internet connection. Instructions on how to do this for various operating systems and devices may be found on our → information pages about Webdav.
Access to your own home directory may also be established via FTP according to

→ the following documentation. With the following change: the path for the FTP server (within FileZilla this is the field 'Standardordner auf dem Server') has to remain empty. If nothing is entered here, you will automatically be connected to your own home directory after login.

Account: Change of Password

You can change the password of your JGU account at the user account self management site. The change will be made via an encrypted connection to the server at the Data Center. Alternatively the change may be made at computer terminals in the Data Center.

→ Change or reset password

Password conditions and restrictions:

For the login, the password must basically meet the following conditions:

  • The new password should contain at least 12 characters and three of the following four categories:
    • Capital letters (A..Z)
    • Lowercase letters (a..z)
    • Numbers (0..9)
    • Special characters (! "$% & / () =? + * # -.,;: _)
  • Your password must not contain your last name, first name, user name (account name) or any part thereof.
  • Do not use any of your previous passwords.
  • Avoid:
    • §, ä, ö, ü, ß, Ä, Ö, Ü, because these characters are not available on all keyboards*.
    • y, Y, z or Z, as these characters are in different places on English and German keyboards. This can cause problems if the computer unexpectedly loads an English / German keyboard layout.
* Note: If possible, do not use any third-party or public computers to log in with your university password.

Additional security check for new passwords and password changes

Since January 2021, an additional security check has been carried out with the database for each new password and each password change. This collects the hashes of the passwords* from password databases that are circulating on the Internet and checks whether the selected password was published in the event of a previous data leak. If so, you will be notified:
  • JGU account page: You will receive a message that the password you entered was part of a data breach and must not be used.
  • When changing the password under Windows using the key combination CTRL + Alt + Del or In such a case, Ctrl + Alt + Del "Change password" appears that the password does not meet the complexity rules. A more specific message cannot be displayed as the ZDV has no way of adapting it.
To ensure that the hashes of the passwords* are not passed on to a third party or website, the entire database was copied directly from the provider and has been running on ZDV's own server since then.

Account: Application or renewal

Please note: Some of the links below lead to pages in German, as work on the English version is still in progress. We apologize for the inconvenience.

A JGU account is automatically created for employees of the university - no separate application is necessary.

Students receive the JGU account with their enrolment and only have to
activate it once after their first enrolment.


On this page you will find information on how to apply for or renew a JGU account for other groups of people.

If you are a visiting researcher, project staff member or student assistant and have not been issued with a user account, please contact the dean's office of your department or the secretariat of your institution to find out who is responsible for the JGU account. To extend your JGU account, you or your supervisor should also contact one of the JGU account managers at your institution.

...may turn to the check-out counter of the central library to apply for a suitable account.

The university library account for external users only serves for printing within the university library and has no further privileges, i.e. you cannot use it for mailing, login at the Data Center, using terminal servers, VPN, WLAN etc.

Members of staff of the university hospital receive their JGU account from the person in charge of accounts of their particular clinic. Please contact the administration of the clinic, the person in charge of its IT or your supervisor.

Institutions that have not yet notified us about a person in charge of accounts may do so by sending an e-mail to → .

At this time we are sorry to say that we cannot hand out any new accounts to members of staff of a training hospital of the university of Mainz. If you have any enquiries about that, please ask the → department of legal matters of the university.
Accounts for members of staff of all external institutions are administrated by the institution itself - please turn to the secretariat or the person in charge of IT at the institution that you are a member of. If need be, you may ask at → which procedure applies at your institution. You will get access, but these accounts do not include an own, personal homepage.
  • Only JGU accounts for natural and living persons can be created. User accounts such as or are not permitted and will be deactivated and deleted by us. Please contact us directly if you have created such a JGU account in the past and would like to continue using it.
  • Due to existing licence agreements, please ensure that the JGU accounts are correctly assigned to the various organisational units (e.g. lecturers, student assistants or guests).
  • The allocation of JGU accounts to guests must be in the interest of the university - e.g. in order to be able to work on joint projects. Granting JGU accounts to guests for their own use, without reference to the university, is not permitted.
  • First name, last name, date of birth and the personal email address (NEW) must be entered with the correct values.
  • Persons who already have a user account as a staff member may not obtain an additional JGU account via this tool.
  • Expired user accounts of employees automatically receive the status "guest account", so that a renewal can take place if necessary, provided that the continued use of the JGU account is in the interest of the university.
  • Only one JGU account may be created for each person - i.e. not several guest, student. This means that there may not be several guest, student assistant or lecturer accounts for the same person.
