**H2K Application**

Private key in application

This is a secret code used to access your account in the application. It's like a password for your personal account. It should not be disclosed to anyone—not even the creators of the H2K app have the private key to your account.

Public key in application

This is a unique code used to identify a user in the application. It's like a login for your personal account. You can safely share it with others so they can add you as a signer in their wallet.

Mnemonic Phrase in the Application

his is a sequence of words that helps users restore access to their account in the application. It is created to remember and securely store the private key.

Authorization in the Application

Authorization is the process of verifying and confirming a user's identity to grant them access to specific features or data in the application. It is usually done using identification factors such as a password, PIN, fingerprint, facial recognition, or other biometric data. In the application, authorization is done through Importing a Mnemonic Phrase or a Private Key.

Importing a private key

This is the process of adding a private key to a crypto wallet or another application to gain access to the associated crypto assets. This is done when you need to restore access to your account or import it to a new device. After importing the private key, you can use the account.

Exporting a private key

This is the process of extracting a private key from a crypto wallet or application to save it or use it elsewhere. Exporting a private key might be necessary if you want to create a backup of the key or use the wallet on another device. When exporting a private key, it's important to keep it in a secure place to prevent unauthorized access to your crypto assets.

Signer in application

A person who has the right to sign and authorize transactions on a multisignature wallet. They are the participants who must agree and sign the transaction before it is executed and added to the blockchain. Multisignature wallets usually require approval from a certain number of signers to ensure security and prevent unauthorized operations. For example, if the wallet requires three signers, to complete a transaction, you need approval from all three participants.
