In order to secure the access to your user account, you can activate two-factor authentication (2FA) for your logins.

With two-factor authentication you need to provide a one-time password (OTP) sent to your cell phone when you sign in, in addition to your logon details (e-mail address and password). With this sign in procedure you can achieve strong authentication.

Go to your profile to activate the feature. You need to add your cell phone number before you can activate the feature.
