Threema Gateway is a prepaid service. After registration, you can test the gateway for free, recharge your credits and request your custom IDs. Credits can be purchased via bank transfer, credit card, PayPal or bitcoin. Sign up now.
Custom IDThreema 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.
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 available modes before choosing.
