# Private Key Management

Multis does not store your private keys, and we never will. Instead, Multis currently offers two types of key management to control accounts. 

* External key management
  * Integration with external wallet solutions such as [Metamask](https://metamask.io/) or [Ledger](https://www.ledger.com/)
* Internal key management
  * Integration with [Torus customauth](https://customauth.io/) (frontend embedded private key) to offer a seamless experience

The key is only used for signing purposes.

### What happens if one owner loses their private keys? 

**If you are connected with an external key (Metamask or Ledger):** This would only occur to a user associated with an external key (Metamask or Ledger). In this case, the admin would remove the previous owner and add them again with another email address. 

**Suppose you are connected with an internal (Torus) key**. You can't lose your key because Torus has it, but you can lose access to your email, preventing you from accessing your private key from Torus.

In this case:

* You can manually back up your private key (carefully, put it in a safe place)
* Get an admin to invite you to join Multis with a different email address
