### How it works

As shown in the diagram, Mixin Messenger’s MPC wallet consists of three key shards:
* PIN Shard: One shard is associated with the user’s PIN code.
* Account Shard: The phone number, mnemonic phrase, or recovery contacts are linked to the same key shard.
* TIP Shard: A shard is stored via the TIP decentralized key network.

The key shards are ultimately combined to form a complete private key stored within the device’s **TEE** (Trusted Execution Environment), ensuring no risk of leakage.

### FAQs
* What’s the Difference Between Registering with a Mnemonic Phrase or a Phone Number?
Registering with a mnemonic phrase offers **better privacy** than using a phone number, but managing a mnemonic phrase yourself can be challenging and carries the risk of leakage or loss.

* Is a Mnemonic Phrase More Secure Than a Phone Number?
**Not necessarily**. If you **cannot** securely manage your mnemonic phrase, we recommend continuing to use a phone number.

* If I register my Mixin account with a phone number, do I need to back up a mnemonic phrase?
It’s not mandatory. If you cannot manage a mnemonic phrase securely, we recommend using a phone number.

* Can I Use Both a Mnemonic Phrase and a Phone Number Simultaneously?
**Yes**. If you registered your Mixin account with a mnemonic phrase, you can add a phone number in Settings > Account > Security > Recovery Kit. Once added, you can log in to the same account using the phone number.

* How Do I Set a Recovery Contact for an Account Registered with a Mnemonic Phrase?
You **cannot** directly set a recovery contact for mnemonic-phrase-based accounts. You **must** first **add a phone number** to the account. After adding a phone number, you can then set up recovery contacts.
