By default, this security method is enabled and it works very simply. The moment you log in to the portal with your username and password, a verification code is immediately sent to the email address of the account holder. You enter this code and then you are immediately logged in.
Note: Some email providers, for example gmail, do not continuously load new email messages. This makes it seem like you didn’t receive the email, even though you did. Usually you can also download new emails manually via the Settings or a ‘Synchronize’ button. The verification code is valid for a maximum of 1 hour!
When the code is entered incorrectly 5 times, the account will be blocked. In such a case, you should contact customer service.
