Custom ID

Threema Gateway lets you request your personal, custom ID. All IDs that are used on Threema Gateway start with an asterisk (*) and consist of 8 characters in total. Example ID: *THREEMA. You can personalize your custom ID by setting a profile picture that is shown instead of the generic Business icon.
Threema App
The Threema app displays Gateway contacts with a generic business icon and a custom profile picture.

Options

You can choose between two modes: BASIC and END-TO-END. Threema strongly recommends END-TO-END mode. It guarantees highest security and offers more features.

Switching modes is only possible at additional cost and the private key cannot be changed. Therefore, please carefully weigh the pros and cons of the the available modes before choosing.
