One of the ways to get new credentials is the Get new credentials option. This option allows you to change your device password (e.g. when sensor stops working and you need to connect another device instead).
Please be noted that the Platform does not save the credentials due to security.
If you forget your credentials, the same action will be applied as shown below.
Note: In case of connecting new physical device there is no need to create new device manifest. Previously described device manifest needs to be assigned to it.
As informed above, your new device password will invalidate the previously generated ones and will put the device offline.
