The authentication page on which you must enter the generated one-time password (called "token" here) looks like this:

First decide on a variant of 2FA. If you want to use an authenticator app, install it from the relevant app store and you can get started straight away. If you need a hardware token, please contact the BTU helpdesk during telephone hours (Mon-Fri 8-15) or by email. A hardware token can be issued there.

Your BTU account has already been created for you. You will now be asked to choose a secure
password.

You will now be taken to the 2FA Authenticator selection screen.

For two-factor authentication at the central web services of the BTU, you must now select the method for generating one-time passwords. You can between the software solution (see: Which authenticator app should I use?) or the hardware token.

If you have opted for the software solution, scan the QR code with your smartphone.
You will now be prompted to generate a new one-time password with your app.

If you have a hardware token, enter the serial number. Only tokens issued by the BTU for your employees can be used.

You will now be asked to generate a one-time password to verify that everything is working correctly.

The 2FA setup is now confirmed.
A page with emergency codes and a QR code is displayed once. You can scan this QR code with your Authenticator app if you prefer to use your smartphone to generate one-time passwords instead of the hardware token.

Remember your emergency codes well - save them in your password manager, for example. An emergency code can be used as a replacement for a one-time password, for example if you need to set up a new authenticator. Like the token-generated one-time passwords, each emergency code is only valid once!
Print out this page and keep it in a safe place where only you can access it!

If you now click on "Next", you will see all the information about your BTU account, such as user
name (login), password validity, e-mail addresses and 2FA device.

Your BTU account is now activated and 2FA is set up.

Log in to the BTU account web portal: https://www.b-tu.de/account/ and select "Manage 2FA token".

For two-factor authentication, you must now select a method for generating one-time passwords.
You can choose between the software solution (see: Which authenticator app should I use?) or the
hardware token.
If you have a hardware token, enter the serial number (back of the device) here.If you would like to use software, please leave the field blank and continue.

Now scan the QR code with your chosen app and then generate a one-time password to check that it works correctly.
The six-digit one-time password is only valid for a short time (30 seconds). If the one-time
password disappears before you can enter it, you must generate a new one.

If you want to use a smartphone app to generate one-time passwords in addition to the hardware token, install a suitable app and scan the QR code. Then generate a one-time password for verification and continue .

Confirmation of the 2FA setup

A page with emergency codes, a link to a test page and a QR code is displayed once. You can scan this QR code with your Authenticator app on your smartphone if you prefer to use your smartphone to generate one-time passwords instead of the hardware token.

Remember your emergency codes well - save them in your password manager, for example. An emergency code can be used as a replacement for a one-time password, for example if you need to set up a new authenticator. Like the token-generated one-time passwords, each emergency code is only valid once!
