Top 15 XenForo - Threema Gateway Alternative and Similar Softwares | Dec 2024

This add-on integrates the secure instant-messaging app Threema into the forum software XenForo. Using the Threema Gateway it offers three new two-step authentication (also called two-factor authentication or "2FA") modes for users and admins.

When the two-step authentication was introduced into XenForo many server admins asked for SMS support. This was my inducement to create this add-on. But instead of using SMS - which is not suitable as it is insecure - I thought one can also just use a well-known, secure instant messaging app.
