Two factor authentication

First you have to click on your username in the top right corner and select the "Change password" function. 

 

 

 Here you have the option to choose between 3 possibilities to activate the two-factor authentication. 

 

 

 If you want to choose option 3 “Text Message”, you have to deposit your phone number: 

 

 Select Profile 

 

 

 

 

   

 

 

 Add your phone number to your profile 

 

 

 

 

   

 

 Now you can choose the button “Security” and choose option 3 “Text Message”. 

 

 

 After you selected the option “Text message” there is going to appear the following pop up. You are receiving a text message with a verification code. 

 

 

 Now you can see, that the status of the two- factor authentication is green and “On”. 

 

 

 The other two options are self-explanatory.
