Change password After logging in, navigate to “Personal Settings” via the person icon. You can change your password in this section.
Reset password You can reset your password using the “Forgot password?” function on the OZG-RE homepage by entering your email address. You will receive a link by email which you can use to specify a new password.
The email address can only be changed by the appropriate administrator (in the user management section). Contact your administrator.
First, sign directly into the OZG-RE, then select “Manage company account” from the dropdown menu at the top left of the screen. You can then edit your company information. To save your changes, click on “Update”.
If you have signed into the OZG-RE via “Mein Unternehmenskonto”, the company information you provided there (e.g. company address) will have been automatically transferred to the OZG-RE. If the company information has been transferred in this way, the “Mein Unternehmenskonto” logo will be displayed on the “Manage company account” page of the OZG-RE.
In this case, it will only be possible to edit your company information via the “Mein Unternehmenskonto” user account. The fields for entering company information in the OZG-RE will be locked. It will only be possible to synchronise and update the company information in one direction: from “Mein Unternehmenskonto” to the OZG-RE – not vice versa.
First, sign directly into the OZG-RE, then select “Manage company account” from the dropdown menu at the top left of the screen. You will then have the option to delete your company account, but only if you have administrator rights. Please note that deleting a company account will also delete all the user accounts connected to it. To delete the account, click on “Delete company account”, then confirm by clicking “Delete”.
If you have signed into the OZG-RE via “Mein Unternehmenskonto”, it will not be possible to delete your OZG-RE company account here. Instead, you must delete it via the “Mein Unternehmenskonto” user account.
