Usually **your teacher** is going to **sign you up** and you will recieve one or two emails containing information on how to login.
You will recieve access to the Teaching Hub usually for 6 month. Can be extended for good reasons or until a teacher signs you up again.
### You recieved two Emails

Use these to login to the server and change the password to something better and still something that is safe:
```
ssh [user]@srvx1.img.univie.ac.at

```
Dear TeachingHub User Monkey
Some of your user information has been updated.
TeachingHub Account Specification:
servers: https://srvx1.img.univie.ac.at
username: monkey
password: ABCDEFGHIJK (signed in, click on user name, upper right corner)
Email: a000000@univie.ac.at
Secret: 1A2B3C4D5E6F7G8H
Please note that the TeachingHub is open from the web.
Two-factor Authentication is required. Download one of these apps and use your secret to generate TOTP (Time based One Time Passwords).
Authy (https://authy.com/download/)
FreeOTP (https://freeotp.github.io/)
Google Auth (https://play.google.com/store/apps/details?id=com.google.android.apps.authenticator2)
...
```
You need to download one of these apps:
- [Authy](https://authy.com/download/)
- [FreeOTP](https://freeotp.github.io/)
- [Google Auth](https://play.google.com/store/apps/details?id=com.google.android.apps.authenticator2)
- or any other (search `2fa apps` and you will find plenty)
I recommend using your phone and an app there, as this is the most secure way. And with you phone you can scan the qr code, which looks like this:
<img src="Documentation/teachinghub-qrcode.png" width="300px">
When you scan to your Authenticator App, it will automatically get the details (username, Secret) required to generate every 30 seconds a Time-based One Time Password (TOTP). Like this:
![](Documentation/teachinghub-authenticator)
The combination of username, password and TOTP needs to be used to sign in:
![](Documentation/teachinghublogin)
This sounds all really complicated, but I promise this will be easier from time to time. Don't forget that this for our all security and your contribution is appreciated! Thanks.
