# First steps - How to use Matrix?
|
||||
|
||||
## Matrix-Login with ZIH account
|
||||
|
||||
Members and members of the TU Dresden (of course also students) can use their **ZIH login** to communicate with members of the TU Dresden and other universities and other Matrix users (e.g. academic partners) via chat and audio/video telephony in compliance with the relevant legal and regulatory provisions on data protection and IT security.
|
||||
communicate.
|
||||
|
||||
<span class="tip">
|
||||
We recommend using the Element desktop client, because this avoids most problems users have with Matrix, e.g. end to end encryption.
|
||||

|
||||
|
||||
After a desktop installation, make sure to use the existing account with the ZIH login and not to create a new account on another server. Here the example of Element:
|
||||
|
||||
|
||||
|
||||
This is done by clicking on **Change**. Then you will not accidentally end up on the wrong server...
|
||||
|
||||
|
||||
|
||||
Now you can manually specify the home server: tu-dresden.de
|
||||
|
||||
|
||||
|
||||
Afterwards the login with ZIH login and ZIH password must be carried out:
|
||||
|
||||
The drop-down menu "Log in with:" should be left at "User name". Then the following entries must be made:
|
||||
|
||||
**Username: ZIH-Login** (only the ZIH-Login, no e-mail address!)
|
||||
|
||||
**Password: ZIH-Password**
|
||||
|
||||
An alternative login, e.g. using the e-mail address, is **NOT** possible during the first, initial login, only after the second login.
|
||||
|
||||
After the first login there is also no e-mail / confirmation mail.
|
||||
|
||||
Analogous to e-mail addresses, this results in matrix addresses with the following structure:
|
||||
|
||||
@ZIH-Login:tu-dresden.de
|
||||
|
||||
|
||||
|
||||
## Convenient use of end-to-end encryption (E2EE)
|
||||
|
||||
Matrix not only encrypts transports to and from the home server (in the data center of TU Dresden) but also allows the use of end-to-end encryption (E2EE). For this, cryptographic keys have to be exchanged between all devices that want to write end-to-end encrypted. This technical necessity sounds and is complicated, but in the meantime it has become very convenient for the users. The many cryptographic keys created by the client are stored on the respective device. If this is a tab in a browser, for example, there is a risk that this tab will be closed unintentionally. Then all encrypted contents are no longer readable. To prevent this from happening, a key protection is offered on the home server of the TU Dresden, on which (protected with a security phrase (or security key that can be calculated from it) all cryptographic keys are stored encrypted.
|
||||
|
||||
{{% notice info %}}
|
||||
It is highly recommended to use this key backup (with a secure security phrase which is NOT your ZIH password)!
|
||||
{{% /notice %}}
|
||||
|
||||
|
||||
|
||||
Alternatively, instead of the security phrase, you can also have a security key generated that serves the same purpose as the security phrase. Furthermore, the security key is generated in addition to the security phrase and should be kept safe and retrievable as an emergency key (e.g. save it as .txt file AND print it out)
|
||||
|
||||
|
||||
[Other important settings]({{< relref "settings/_index.en.md" >}}) may improve your Matrix experience!
|
||||
|
||||
|
||||
## Requests to setup the key backup
|
||||
|
||||
|
||||
|
||||
If you skipped the request to setup the key backup, the next screen would look like this:
|
||||
|
||||
|
||||
|
||||
Key protection is highly recommended for worry-free end-to-end encryption. For this reason, a smaller tooltip will prompt you to set up the encryption even after you skip further:
|
||||
|
||||
|
||||
|
||||
If you omit this here as well, you will get a last warning if you log off consciously. If no key backup is set up at the latest, encrypted calls that may have already taken place cannot be accessed later. If the tab is closed, this also corresponds to a logout.
|
||||
|
||||
|
||||
|
||||
Avoid this situation by setting up a key backup!
|
||||
|
||||
## Matrix-Login without ZIH account
|
||||
|
||||
A registration of accounts (as known from other matrix servers) is not possible here at the TU Dresden, because only persons with ZIH login can use the service. The TU Dresden is not a communication service provider.
|
||||
|
||||
For scientific cooperations with colleagues without a ZIH account there is the possibility to [apply for a ZIH guest account](https://tu-dresden.de/zih/dienste/service-katalog/zugangsvoraussetzung), which also entitles to use Matrix.
|
||||
|
||||
However, the federation with the Matrix servers of other scientific or civil society institutions will soon be possible (analogous to the existing e-mail federation). Example servers with which communication is already possible are:

# Matrix at envs.net
|
||||
Matrix is a free and open, secure, decentralized protocol for real-time communication, also known by the name of one of its clients, Element.
|
||||
|
||||

|
||||
|
||||
In recent years, the need for supporting digital tools for team collaboration has increased. A central tool is a team chat. According to Wikipedia, a chat refers to "electronic communication by means of written text in real time, usually via the Internet". ([Source](https://en.wikipedia.org/wiki/Chat)). With a messenger team members can make each other aware of current information and especially share links (*hyperlinks* / *links*) for further collaboration (e.g. for finding appointments, collaborative writing, planning events, editing data, code, mind maps,).

### Questions and Contact
|
||||
|
||||
The ideal is to deal with problems in a transparent way, from which all others can learn. This can be done by describing the situation in the ENVS main room - here problems and solutions can be discussed together:
|
||||
|
||||
[#envs:envs.net](https://matrix.to/#/#envs:envs.net)
|
||||
|
||||
<span class="note">
|
||||
For some anomalies you can try to empty the cache and reload everything:
|
||||
</span>
|
||||
|
||||
`Settings > Help & About > Clear Cache and reload`
|
||||
|
||||
<span class="note">
|
||||
Current maintenance is announced in the matrix room [#home:envs.net](https://matrix.to/#/#home:envs.net) and

[#status:envs.net](https://matrix.to/#/#status:envs.net).
