Threema for Android. The signs of security levels

Another feature at threema are the three different levels of security for tap-proof communication and the identity of your opponent, which are also provided with its own icon. The security levels are represented by points on a traffic light system. What exactly are these points, we do not want to deprive you of course.


 First security level (red)

This is the weakest level of security. The user ID of your contact and the corresponding public key is retrieved directly from the server. A matching contact in your address book has not been found, so the identity of this contact can not be clearly verified.

threema-status-orange 2nd level (orange)

This symbol is probably most commonly seen in association with your contacts. The corresponding user was found in your address book, the associated data (e-mail address and / or phone number) were also verified by the threema servers. While there is still the possibility that it is not indeed to the desired contact, but this is unlikely.

threema-status-green 3. security level (green)

If everything is in the green zone, that of the sender's identity has been properly verified. The only exception: The smartphone this contact has been stolen or hacked. Display these three points are you, but only if it confirms the public key that person by scanning the corresponding QR codes. In contacts with the highest security level you can assume that it is indeed the appropriate person.
