TRAIT Vault is a safe wallet with a limited set of features. It's suitable for storing private keys of addresses for owners and admins of AppAgents. Additionally, it's a good solution for storing a large amount of on-chain assets.
TRAIT Vault can only be used to create and manage owner and admin addresses, it cannot store or manage keyless addresses such as AppAgent addresses or Transactional Addresses since theses accounts have no keys and cannot be used to sign transactions.
The app can be downloaded on the iOS App Store (soon) or the Android PlayStore (soon) depending on your mobile device. The source code of all the versions can be downloaded on the GitHub repo (soon).
You can create a new account directly within the Vault app (Add Key Set > Add new Key Set). This will generate a new mnemonic seed phrase on the app.
Alternatively, you can import a new account into the app using a seed phrase generated elsewhere with a compatible account generation scheme.
For example, you can have an air-gapped laptop with the Subkey tool installed and generate a new account there. The seed phrase of that account can be imported into the Vault App (Add Key Set > Recover Key Set).

Remember to always check for metadata updates before signing transactions. See this article to learn how to sign transactions and this article on how to easily add new chains and do metadata updates using the Vault app.
The procedure to sign transactions with the Vault app is as follows:
The wallet or browser extension will show a QR code encoding the information about what you are going to sign.
After scanning the QR code with the Vault app, you will be presented with decoded information about what you will sign. Make sure the information matches what you intended to sign. If something does not feel right, do not sign.
Check this page for more information and contact the Polkadot Support Team.
If the information shown by the Vault app is correct, you can present the QR code (signature) to the camera on your laptop to sign for the transaction.
Even though Polkadot Vault is a safe airgapped wallet, please follow all security practices listed here to be safe.
