Torus splits a user’s private keys into shares across a network of nodes, and allows a user to retrieve this using natural login mechanisms like social authentication. You need access to more than half of the shares to reconstruct the private key.
2 points make a line right? Draw a straight line and write down the coordinates of 3 points. Erase the line.
You now need at least 2 out of 3 of the points are required to reconstruct the line.
This is a 2/3 Shamir secret sharing of the original line.
Our nodes have managed volumes and snapshot policies to ensure that key shares are not lost. We also have coverage that extends to key loss due to technical failures.
No, the initial login only requests for the minimal public information, which you can see during the OAuth popup screen by the 3rd-party provider. The purpose of the login is only for verification of your identity, not for access to your personal information.
We log you out of your 3rd-party account immediately after your identity is verified. The only information that is accessible to these 3rd-party login providers is that you were logged in (and logged out) with Torus.
It is definitely possible but keeping the user logged in for just that session gives better privacy guarantees for users. There is no easy way for Torus to ensure that users are logged out by the DApp, so we opted to keep user sessions self contained.
Most Oauth providers already solve this problem by auto-approving the login request if the user logged in recently, and it may not even require user interaction. For example, for Facebook login, users do not even need to click anything if they have recently logged in.
There are several restrictions. Some integrations are possible (eg. native support, Chrome extensions), whereas others are not (eg. using Torus wallet in a server context). Right now, we only have browser based support.
We are currently running the network as a permissioned network, so there is a whitelist process, please reach out at email@example.com
