Operation of the LAUDA devices via the web server is carried out in the
same way as operation via the operating unit on the device. If required, please
refer to the respective descriptions of operation provided in this operating
manual.
The operation of the device via the LAUDA Command App is very similar
to the remote control Command Touch, whose operating instructions can
be downloaded from our homepage. Open the LAUDA homepage, tap

Cookies must be activated if you use a web browser. The device creates a
cookie with a connection-specific token which is generated during the initial
mutual authentication. This information is lost if the cookie is rejected or
deleted. Authentication must then be repeated the next time a connection is
established.
Contact your network administrator if you require further assistance in
implementing secure access.
Two-Factor Authentication is an authentication using a combination of two
different and independent paths. The user is checked by the remote station
and the remote station is checked by the user.
In the case of LAUDA, a user with automatically generated access data is
created in the constant temperature equipment during the 2FA. The access
data is stored in the App in the form of a token and as a cookie in the web
browser. The token is valid for 6 months. In addition to this, all registered
users (tokens) can be deleted via the Master on the constant temperature
equipment. The user must repeat the 2FA in these cases.
The 2FA must be performed:
n
At the first connection.
n
When the token is no longer valid.
n
When the cookie is no longer valid.
n
If the cookie has been deleted in the browser or has not been saved.
The user is automatically prompted by the App or the web browser if a
2FA is necessary. A 6-digit one-time password is shown on the display of
the constant temperature equipment when performing the 2FA. This is valid
for 5 minutes. Type the code displayed in the Web client and confirm your
entry. The connection is continued if authentication is successful. If an error
occurs, check whether your entry was correct.
